Add collaboration token issuance and connection authentication (#34)
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
