agent_coder 7f9f6c7585 fix(mcp): не нормализовать текст под маркой code в сносках (порча code-литералов)
Ревью #422: безусловная нормализация переписывала в ASCII и текст inline-code
внутри сносок (кавычки/тире/спецпробелы) — для code-литерала это не типографика,
а изменение смысла (эмпирически на raw-JSON путях: code-нода "a—b «x»" -> "a-b").
normalizeDefinitionText теперь пропускает текст-ноды с маркой code (verbatim), и
краевой trim определения тоже не трогает крайние code-ноды. footnoteMergeKey
читает сырой текст code-нод -> сноски, различающиеся только глифами в коде, НЕ
сливаются, а форки в прозе по-прежнему сливаются. Тесты: code verbatim +
непослияние по code-глифам.

agent_coder 91c4cc925a feat(mcp): детерминированная нормализация текста сносок + склейка форков по нормализованному тексту
Новый чистый модуль footnote-normalize-merge.ts (normalizeAndMergeFootnotes):
нормализует текст определений сносок (типографские кавычки->ASCII, тире->'-',
NBSP/спецпробелы->пробел, схлопывание пробелов, trim) и сливает определения с
совпавшим нормализованным текстом, перевешивая ссылки на канонический id;
дубли-сироты добивает canonicalizeFootnotes. Ключ слияния attrs-aware
(footnoteMergeKey/stableAttrs) — сноски с одинаковым текстом, но разными attrs
марок (напр. link.href) НЕ сливаются (защита от потери target). Пасс вызывается
строго ПЕРЕД canonicalizeFootnotes на 5 write-путях MCP (markdown-импорт,
updatePageJson, copyPageContent, docmost_transform, insertInlineFootnote).
Глиф-карты продублированы из comment-anchor.ts (там private+завязаны на golden).
Идемпотентен, чистый (deep-clone), scope строго внутри footnoteDefinition.

closes #419

/**
* Collab-token cache TTL in milliseconds (issue #435). Read fresh from the
* environment on every mint — like collab-session.ts readConfig — so tests and a
* live rollback can change it without reloading the module.
*
* Why a cache at all: the live CollabSession registry (#400/#431) keys sessions
* on (wsUrl, pageId, collabToken) for identity isolation (invariant 4). But BOTH
* collab-token sources mint a FRESH token per mutation — the in-app provider
* re-signs a JWT whose iat/exp (seconds) changes every second, and the external
* MCP POSTs /auth/collab-token each call — so the token in the key changed on
* every op and the session was almost never reused (connect-storms, 25s
* timeouts, zombie sessions). Caching the token per-client keeps the key stable
* across a burst of mutations so ONE session is reused.
*
* Default 5 min: well under the 24h collab-token lifetime AND <= the collab
* session max-age (10 min, MCP_COLLAB_SESSION_MAX_AGE_MS), so the
* permission-staleness window is not widened beyond what #431 already accepted.
* The rollback knob is an EXPLICIT 0 (or a negative number): that DISABLES the
* cache — an exact fetch-per-call legacy path, mirroring how idleMs<=0 disables
* the session cache. Unset OR unparseable (e.g. a typo like "5min", "abc") falls
* back to the 5-min default with the cache ON — parseInt yields NaN, which is
* treated as "not configured", not as "disabled". So to turn the cache off you
* must set the value to exactly 0, not to garbage.

/**
* Deterministic server-side NORMALIZATION + MERGE of footnote DEFINITIONS
* (MCP, PURE).
*
* Problem (#419): footnotes with the same meaning but different GLYPHS —
* typographic quotes («…»/“…”) vs ASCII "…", em/en-dash vs `-`, non-breaking
* space vs normal space, differing space counts — are not recognized as equal
* and "fork": two definitions appear where the author meant one. The existing
* de-dup paths miss this: `footnoteContentKey` (footnote-authoring.ts) only
* collapses ASCII whitespace (quotes/dashes/NBSP untouched), and
* `canonicalizeFootnotes` keys purely by `attrs.id` (the two forks have
* different ids), so neither glues the forks together.
*
* This pass fixes that DETERMINISTICALLY on the MCP write-paths (an LLM
* instruction gives no glue guarantee). It:
* 1. Normalizes the TEXT of every `footnoteDefinition`'s text nodes IN PLACE
* (typographic quotes -> ASCII "/', dashes -> `-`, NBSP & friends ->
* normal space, whitespace runs collapsed, whole-definition edges
* trimmed) — unconditionally, for ALL definitions, KEEPING their marks.
* 2. Computes a MERGE KEY per definition (normalized text + an ATTRS-AWARE
* inline-mark signature, via the local `footnoteMergeKey`), so notes that
* read the same but differ in formatting (bold vs plain) OR in a mark
* attribute (a `link` with a different `href`, differing `code`/`highlight`
* attrs) are NOT merged. See `footnoteMergeKey` for why this diverges from
* the shared type-only `footnoteContentKey`.
* 3. Maps every duplicate definition id to the FIRST (document-order)
* definition's id and re-hangs `footnoteReference` nodes onto it.
*
* Duplicate definitions keep their original ids but now have NO references, so
* the canonicalizer that runs immediately after this pass removes them as
* orphans and derives the single tail list + numbering. This pass therefore
* MUST run BEFORE `canonicalizeFootnotes(doc)` at every write-path call-site
* (see the enforcement rule in `footnote-canonicalize.ts`).
*
* Accepted tradeoff: the exact typographic glyphs of the SURVIVING footnote are
* rewritten to ASCII, in exchange for a GUARANTEED merge. Scope is strictly
* INSIDE `footnoteDefinition` — body text (normal paragraphs) is never touched.
*
* Pure: deep-clones its input, deterministic, idempotent (a re-run is a no-op —
* text is already normalized and references already point at the canonical id,
* so no spurious mutations / git-sync churn).
