fix(page,ai-chat): address PR #200 review — canonical lock UUIDs, changelog, tests

- page.service: lock concurrent re-parents by canonical row UUIDs
  (`movedPage.id`, not the raw client `dto.pageId` which may be a slugId) so
  two opposing moves passing slugIds can't sort into different FOR UPDATE
  orders and deadlock (#159).
- CHANGELOG: add [Unreleased] entries — Fixed #159 (serialized concurrent
  moves + in-tx cycle re-check), Added #190 (model-friendly tool-input errors).
- page.service.spec: hoist the duplicated `makeChain` trx-stub Proxy into one
  module-level helper (was 3 copies); add a move-to-root test covering the
  unlocked else-branch (no transaction opened, updatePage called without a trx).
- model-friendly-input.spec: cover the duplicate-path dedup branch in
  formatIssues — a single param with two zod issues is named only once.

 ### Cutting a release
 
-The git tag is the source of truth for the displayed version (the client UI reads `git describe --tags` via `vite.config.ts`); the `package.json` bump is metadata that backs the server `/version` endpoint (`version.service.ts`).
+The git tag is the source of truth for the displayed version (UI reads `git describe --tags`); the `package.json` bump is metadata only. Steps:
 
-**Golden rule — tag on `develop` first, merge to `main` afterwards.** Cut the version-bump commit on `develop`, put the tag on *that* commit, and push it. Merge `develop` into `main` later (it does not block the tag or the release). Because the tag is in `develop`'s ancestry from the moment it is created, `git describe` on `develop` — and the `ghcr.io/vvzvlad/gitmost:develop` image — reports the new version immediately, with **no back-merge dance**. Do **not** tag `main`'s merge commit; that is the mistake described in the pitfall below (we hit it twice).
-
-Steps:
-
-1. Make sure `develop` is up to date, clean, and pushed to **both** remotes (`git status`; `git push gitea develop && git push github develop`).
+1. Make sure `main` is clean and pushed (`git status`, `git push`).
 2. Pick `vX.Y.Z` (SemVer): **minor** bump for a batch of features, **patch** for fixes only. Review what landed with `git log <last-tag>..HEAD --no-merges`.
-3. Bump `"version"` to `X.Y.Z` in the **root** `package.json`, `apps/client/package.json`, and `apps/server/package.json` (keep all three in sync). Leave `packages/mcp` alone — it is versioned independently. Commit **on `develop`** with the bare version as the subject, e.g. `0.94.1` (matches past bump commits).
-4. For a real release (skip for a bare hotfix tag), update `CHANGELOG.md` (Keep a Changelog format): add a `## [X.Y.Z] - YYYY-MM-DD` section summarising `git log vPREV..HEAD --no-merges` grouped by type (Breaking / Added / Changed / Fixed / Removed), and the `compare/vPREV...vX.Y.Z` link at the bottom. Fold it into the bump commit.
-5. Tag that develop commit with a **lightweight** tag (existing release tags are lightweight): `git tag vX.Y.Z`.
-6. Push the branch **and** the tag to **both** writable remotes — `git push <branch>` does **not** push tags, and tags are per-remote:
-   ```bash
-   git push gitea develop && git push gitea vX.Y.Z
-   git push github develop && git push github vX.Y.Z
-   ```
-   Pushing the `v*` tag to `github` triggers `release.yml` (multi-arch GHCR images + a draft GitHub Release). The tag *must* exist on `github`, because the `:develop` and release images are built there by GitHub Actions and `git describe` on the runner only sees the tags present on `github` (not your local clone or `gitea`).
-7. Merge `develop` into `main` when ready (commonly later — this does not gate the release):
-   ```bash
-   git checkout main
-   git merge --ff-only develop   # or a merge commit if fast-forward is not possible
-   git push gitea main && git push github main
-   ```
-   The tag is already reachable from `main` (it lives in the `develop` history that `main` now contains), so `main` reports `vX.Y.Z` too — no extra tagging needed.
+3. Bump `"version"` to `X.Y.Z` in the **root** `package.json`, `apps/client/package.json`, and `apps/server/package.json` (keep all three in sync). Leave `packages/mcp` alone — it is versioned independently. Commit with the bare version as the subject, e.g. `0.91.0` (matches past bump commits).
+4. Update `CHANGELOG.md` (Keep a Changelog format): add a `## [X.Y.Z] - YYYY-MM-DD` section summarising `git log vPREV..HEAD --no-merges` grouped by type (Breaking / Added / Changed / Fixed / Removed), and add the `compare/vPREV...vX.Y.Z` link at the bottom. Fold the bump + changelog into the release commit.
+5. Tag the release commit with a **lightweight** tag (existing release tags are lightweight): `git tag vX.Y.Z`.
+6. Push commit and tag: `git push origin main && git push origin vX.Y.Z`. Pushing the `v*` tag triggers `release.yml` (multi-arch GHCR images + a draft GitHub Release).
+7. **Back-merge the release into `develop`** so develop builds report the new version: `git checkout develop && git merge --no-ff main && git push origin develop` (push to Gitea as well if that is the canonical remote).
 
-#### Pitfall: tagging `main` instead of `develop` (the mistake to avoid)
+#### Why develop keeps showing the *previous* version (and why step 7 matters)
 
-`git describe --tags --always` (see `vite.config.ts`) walks **backwards from the current commit** and picks the **nearest tag reachable in that commit's ancestry**, then appends `-<commits-since-tag>-g<short-hash>`.
+The UI version is `git describe --tags --always` (see `vite.config.ts`), which walks **backwards from the current commit** and picks the **nearest tag reachable in that commit's ancestry**, then appends `-<commits-since-tag>-g<short-hash>`.
 
-The wrong flow we fell into twice: merge `develop` into `main` *first*, then tag `main`'s **release merge commit**. That merge commit is **not** in `develop`'s history, so `git describe` on `develop` cannot see the new tag and falls back to the *previous* reachable one. Result: every develop build — and the `ghcr.io/vvzvlad/gitmost:develop` image — keeps reporting e.g. `v0.93.0-NNN-g<hash>` even though a release was "cut". Tagging on `develop` (the golden rule above) avoids this entirely: the tag is in `develop`'s ancestry from the start, and `main` still gets it once `develop` is merged in.
+The release tag (`vX.Y.Z`) is created on **`main`'s release merge commit**, and that commit is **not** in `develop`'s history. So until the release is back-merged, `git describe` on `develop` cannot see the new tag and falls back to the *previous* reachable tag. Result: every develop build — and the `ghcr.io/vvzvlad/gitmost:develop` image — keeps reporting e.g. `v0.91.0-NNN-g<hash>` even though `main` is already tagged `v0.93.0`. This is the classic git-flow pitfall: the version on `develop` does **not** advance just because a release was tagged on `main`.
 
-Second gotcha — the tag must exist on the remote CI builds from. `git describe` names a tag **ref**, not just a commit. The `:develop` and release images are built by GitHub Actions (`develop.yml` / `release.yml`, `actions/checkout` with `fetch-depth: 0`), so the version they print depends on which tags exist **on the `github` remote** — not on your local clone or on `gitea`. `git push <branch>` does **not** push tags; push them explicitly to **each** remote (`gitea` and `github`). A tag that only lives on `gitea` is invisible to the GitHub build.
+Back-merging `main → develop` (step 7) pulls the tagged release commit into `develop`'s ancestry, after which develop builds correctly show `vX.Y.Z-NNN-g<hash>`. If `develop` already drifted (release tagged but never back-merged), just run step 7 now — no new tag is needed.
 
-If you already tagged `main` (or `develop` still shows the old version), recover without re-tagging:
+##### The tag must also exist on the remote that CI builds from (multi-remote gotcha)
 
-1. Make the tagged commit reachable from `develop` — either back-merge `main → develop` (`git checkout develop && git merge --no-ff main`), or confirm the tagged commit is already an ancestor of `develop`.
-2. Make sure the tag exists on `github`: compare `git ls-remote --tags github` with `gitea`, and push the missing one (`git push github vX.Y.Z` / `git push gitea vX.Y.Z`). Pushing a `v*` tag to `github` also fires `release.yml` — expected, just be aware.
-3. Re-run the develop build (`gh workflow run Develop`, or push any commit to `develop`) so `git describe` re-resolves with the tag now in scope.
+`git describe` names a tag **ref**, not just a commit — so the back-merge is *necessary but not sufficient*. The develop image is built by GitHub Actions (`develop.yml`, `actions/checkout` with `fetch-depth: 0`, then `git describe --tags --always`), so the version it prints depends on which tags exist **on the `github` remote**, not on your local clone or on `gitea`.
 
-(There is no `origin` remote here — push to `gitea` **and** `github` explicitly, and always push release tags to both.)
+This repo has two writable remotes — `gitea` (canonical, where commits land) and `github` (where the `:develop` and release images are built) — plus `upstream` (docmost, never push). **`git push <branch>` does NOT push tags**; tags must be pushed explicitly and *to each remote separately*. A release tag that only lives on `gitea` is invisible to the GitHub Actions build: even with the tagged commit fully in `develop`'s history (step 7 done), `git describe` on the GitHub runner falls back to the previous tag it *does* have, so the develop image keeps showing e.g. `v0.91.0-NNN` while `git describe` locally already says `v0.93.0-NN`.
+
+Fix / checklist when develop still shows the old version after a back-merge:
+
+1. Confirm the tag is missing on github: `git ls-remote --tags github` (compare with `gitea`).
+2. Push it there: `git push github vX.Y.Z` (and `git push gitea vX.Y.Z` if it is missing on gitea too). Note: pushing a `v*` tag to `github` also triggers `release.yml` (multi-arch GHCR images + draft Release) — expected, but be aware.
+3. Re-run the develop build (`gh workflow run Develop`, or push any commit to `develop`) so `git describe` re-resolves with the tag now present.
+
+(The `git push origin ...` in steps 6–7 above is shorthand — there is no `origin` remote here; substitute `gitea` **and** `github` as appropriate, and always push release tags to both.)

-  parameter (the JSON Schema contract is unchanged and nothing is backfilled).
-  (#190)
-- **Page move: cycle checks are now atomic and depth-bounded.** Moving a page
-  under one of its own descendants is rejected in the same transaction as the
-  update (closing a TOCTOU window where two concurrent A→B / B→A moves could
-  form a cycle), and the recursive tree-traversal CTEs carry a cycle/depth guard
-  so a pre-existing cycle can no longer spin a query. (#207)
-- **Page/editor robustness batch.** Duplicating a page now copies shared
-  attachments for every referencing page (not just the first); colliding block
-  ids are de-duplicated on import/normalize so MCP addressed edits can't hit the
-  wrong node; transient collab store failures are retried so autosave edits
-  aren't lost; and an out-of-order tree move no longer drops the moved subtree.
-  (#206)
-
-### Security

-- **Public share AI: per-workspace rolling-day token budget.** The anonymous
-  share assistant now caps a workspace's actual token spend (input + output,
-  summed across every accepted turn) over a trailing day, on top of the hourly
-  request cap — so a caller who evades the per-IP throttle still cannot run up
-  the owner's provider bill without bound. Cluster-wide via Redis and FAILS
-  CLOSED if Redis is down; default 1,000,000 tokens/day, overridable via
-  `SHARE_AI_WORKSPACE_TOKEN_BUDGET_PER_DAY`. (#159)
+- **Concurrent page moves can no longer lose a subtree to a cycle.** Two
+  opposing re-parents racing each other (A: X under Y, B: Y under X) could each
+  pass a cycle check built from a stale snapshot and commit a cycle, orphaning a
+  subtree. A genuine re-parent under a concrete parent now serializes: it locks
+  the moved page and the destination parent `FOR UPDATE` in a canonical
+  (UUID-sorted) order — so opposing moves can't deadlock — and re-runs the cycle
+  check INSIDE the transaction against the now-committed state. Same-parent
+  reorders and moves to root keep the lock-free path. (#159)

-/**
- * SECOND cost contour: a per-workspace TOKEN budget over a rolling DAY.
- *
- * The request-count cap above bounds how MANY anonymous calls a workspace
- * admits, but NOT how expensive each one is: one accepted call runs the agent
- * loop up to `stepCountIs(5)`, and every step re-sends the WHOLE client-held
- * transcript (~hundreds of KB) as input, so the provider input alone can be tens
- * of thousands of tokens PER step while `maxOutputTokens` only caps the output.
- * The request cap is also hourly with no daily ceiling, so a steady stream at
- * the hourly cap sustains ~24x its count per day. Counting requests therefore
- * does not bound the owner's actual LLM bill (issue #159, finding #5).
- *
- * This contour caps the SPEND directly: the actual tokens consumed (input +
- * output, summed across all steps of every accepted turn) over the trailing
- * `windowMs` (one rolling day) must stay under `budget`. It is checked BEFORE a
- * turn streams (read-only) and the turn's real usage is recorded AFTER it
- * finishes (`streamText` onFinish). Like the request cap it is cluster-wide
- * (shared Redis) and uses a sliding-window LOG so the day boundary cannot be
- * gamed for a 2x burst.
- *
- * Pre-check is read-only, so a turn already over budget is rejected, but the
- * tokens of an in-flight turn are not yet known and are accounted only once it
- * finishes. The worst-case overshoot past the budget is therefore one turn
- * (bounded by steps x (maxOutputTokens + transcript size)) — acceptable for a
- * cost backstop on an optional anonymous assistant.

- * Centralized input-schema wrapper for every in-app AI-chat tool.
- *
- * THE PROBLEM (#190): when the model issues PARALLEL / batch tool calls it
- * sometimes drops an "obvious" repeated required argument (typically `pageId`)
- * from some of the calls. zod v4 correctly rejects the missing value, but the
- * AI SDK forwards zod's RAW message ("Invalid input: expected string, received
- * undefined") straight back to the model, which is not actionable — the model
- * cannot tell WHICH parameter it dropped or that it must re-send it.
- *
- * THE FIX: keep the exact same validation, but replace the raw zod text with a
- * model-friendly message that names every problematic parameter and tells the
- * model to re-issue the call with all required parameters present. We do NOT
- * guess/backfill the value (a silently-assumed "current page" could comment on
- * the wrong page — cf. #159); the model is simply told to retry correctly.
- *
- * HOW IT WORKS: we build the tool's JSON Schema from the zod shape via
- * `z.toJSONSchema(..., { target: 'draft-7' })` (so the advertised contract —
- * `required` / `description` / field constraints — is unchanged) and hand the
- * AI SDK a custom `validate` that runs `z.object(shape).safeParse(value)`. On
- * failure the AI SDK wraps our returned `Error` in `InvalidToolInputError`, so
- * our clear text is what reaches the model as the tool error.
