First step of docs/git-sync-plan.md. New workspace package @docmost/git-sync vendoring the PURE parts from docmost-sync (HEAD b03eb35): - lib: markdown-converter, markdown-document, canonicalize, docmost-schema, node-ops, diff, and an extracted markdown-to-prosemirror (only the pure marked->HTML->generateJSON path from upstream collaboration.ts; no websocket). - engine (pure, no IO): reconcile, layout, sanitize, stabilize, loop-guard. Ported the upstream pure-module + round-trip corpus tests (vitest): 314 pass, 3 expected upstream known-limitation fails. tsc clean. No server wiring yet. docmost-schema inlines getStyleProperty (as packages/mcp does — @tiptap/core 3.20.4 doesn't export it). IO engine (pull/push/git/settings) deferred to later Phase A/B steps; the editor-ext idempotency gate (plan §13.1) is the next step. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

/**
|
|
* Normalize-on-write helper (SPEC §11 "Резолюция").
|
|
*
|
|
* git diffs byte-for-byte, so writing a page in a NON-fixpoint markdown form
|
|
* would make the next pull re-export it to a slightly different (but stable)
|
|
* form and produce a phantom diff -> churny commits. The converter has a couple
|
|
* of known one-pass asymmetries (a block image after a paragraph adds an empty
|
|
* paragraph; a diagram materializes `data-align`), all of which converge to a
|
|
* fixpoint after ONE `export -> import -> export` round-trip.
|
|
*
|
|
* So at write time we run exactly that one pass and persist the fixpoint form.
|
|
* Already-stable content is unaffected (the pass is idempotent), so re-pulls of
|
|
* unchanged pages produce identical bytes and git sees no diff.
