Revoking write access must terminate live sessions and let a user with
pending offline edits export them rather than lose them silently.

Backend (generic, reused by M5 grants #53):
- packages/shared: POND_ACCESS_CHANGED_CHANNEL, the LISTEN/NOTIFY channel
  shared by api and collab.
- api: PondAccessNotifier emits pg_notify(pond_access_changed, pondId) on
  a permission-relevant change; the single generic seam for revocation.
  Wired into pond soft-delete as the interim trigger (see==modify until
  #53).
- collab: a dedicated-connection LISTEN listener (LISTEN is connection-
  bound, not pooled) that, on a notification, closes every open connection
  to the pond's open pages. Clients then reconnect and the api re-issues a
  token reflecting current access (downgrade to ro, or 403/404). Reconnects
  and re-LISTENs if its connection drops.

Frontend:
- use-collab-provider: a refused token (403/404) on (re)connect sets
  accessRevoked and stops the reconnect loop; exposes discardLocal.
- AccessRevokedDialog: keeps local content visible and offers Markdown
  copy/download (derived from the live editor doc, so offline edits are
  included) and an explicit discard that clears IndexedDB. de+en strings.

Tests: collab DB-backed integration test proves a direct NOTIFY closes a
live session within seconds (AC1) and leaves unrelated ponds untouched;
listener unit tests; api test asserts soft-delete fires the notifier;
web test for the export Markdown derivation.

The collaboration server becomes the writer of page state (ADR 0003,
realtime-collaboration.md §lifecycle):

- onLoadDocument reconstructs a page's Y.Doc from PostgreSQL by applying
  `pages.ydoc_state` and then every `page_updates` row in order, so a page
  with a long update log loads correctly.
- onStoreDocument persists debounced (2 s, max 30 s): it appends the delta
  since the last flush to `page_updates`, periodically merges the log back
  into `ydoc_state` (inline threshold; the session-aware compaction of idle
  pages remains the separate job, #40), refreshes `page_content_cache`
  (plain text / Markdown / HTML / outline via the shared derivation, #24),
  bumps `pages.updated_at`, and keeps `Attachment.pageId` pointed at the
  embedding page (#31). Each flush runs in one transaction and its duration
  is logged.
- The document size ceiling (MAX_PAGE_DOCUMENT_BYTES) is enforced on store:
  an oversize document is not persisted and the clients are notified with a
  stateless error so they can revert.

Persistence is an injected port (PagePersistence): the Postgres
implementation is covered by a DB-backed test (store/load round-trip,
content-cache refresh, a 1000-entry update log, size-ceiling rejection,
not-found), and the hook wiring — two-client sync, survival across a server
restart, and the size-ceiling stateless notification — by an integration
test using an in-memory fake. The collab package gains its own vitest setup
that provisions an isolated `_collab` test database.

The REST `PUT /pages/:id/state` write path stays in place for now and is
retired (410) together with switching the editor to live collaboration in
#36, so the deployed editor is never left unable to save between the two
deploys.

The api mints a short-lived (60 s) HS256 JWT per page open after an interim
permission check; the collab server authenticates every connection with it
(ADR 0003/0007 — the only JWTs in the system).

- packages/shared: browser-safe token schema/types in `collab-token`, and the
  Node `crypto` sign/verify in `token-crypto` behind its own subpath export
  (`@dorfteich/shared/token-crypto`) so the web bundle never pulls in
  `node:crypto`. Only HS256 is produced/accepted; the signature is checked in
  constant time before any untrusted field is read.
- api: `GET /pages/:id/collab-token` (auth-required) returns
  {token, mode, expiresInSeconds}; `mode` is rw/ro via the interim access
  service; issuance is logged at debug level without the token value.
- collab: `onAuthenticate` verifies the token, checks the pageId matches the
  document name, stores {userId, mode} context, and enforces `ro` via
  Hocuspocus' read-only connection flag. Hocuspocus' own signal handling is
  disabled so index.ts remains the single shutdown owner.
- Shared COLLAB_TOKEN_SECRET env for api + collab (compose, dev overlay,
  .env.example, stage docs); a dev default keeps native dev/test/CI running.

Tests: shared token round-trip/rejection; api endpoint e2e (auth required,
claims, 404 for non-members/unknown ids); collab integration via
HocuspocusProvider (valid token connects; expired/tampered/mismatched-page/
wrong-secret rejected; read-only writes dropped, verified with two clients).

Closes #34

Bootstrap apps/collab as a Hocuspocus WebSocket server (ADR 0003):
- pino JSON logging (service=collab) and shared Zod env validation
  (collabEnvSchema); structured connection open/close logs.
- /healthz endpoint (process liveness + PostgreSQL ping) served via the
  onRequest hook, matching the container-internal path and the proxied
  /collab/healthz path; any WebSocket handshake is accepted for now
  (authentication arrives with #34, persistence with #35).
- Dockerfile (ESM workspace build) and a compose service on the frontend
  and internal networks with a healthcheck; dev overlay service and a new
  COLLAB_PORT variable.
- CD builds, pushes, and promotes the collab image; CI builds it on PRs;
  the smoke suite asserts /collab/healthz through the reverse proxy.
- deployment.md/stages.md: proxy routing, per-stage COLLAB_PORT, checklist.

Closes #33

b16d23297e Scaffold pnpm monorepo with lint, format, and test tooling
pnpm workspace with apps/web, apps/api, apps/collab, and
packages/shared; strict TypeScript base config, repo-wide ESLint (flat)
+ Prettier, Vitest per package, and root scripts lint/typecheck/test/
build. @dorfteich/shared ships a first health-response helper consumed
by apps/api to prove workspace linking. Existing markdown docs are
reformatted once by the new Prettier setup.

Closes #1
