claude code agent 227 24b903aaf3 build(git-sync): land the @docmost/git-sync package into develop, code-only (#326 step 1 / PR-A)
The git-sync converter + engine source lived only on the #119 branch; develop
had just the dead compiled build/. Bring the whole package (src + ~700 tests)
onto develop under CI, with NO consumer wired — git-sync stays fully inert in
develop (nothing in apps/server imports it), so runtime behavior is unchanged.
This unblocks #293 (extract the shared converter package from the landed source)
and lets #119's functionality land LAST, already writing the canonical format
(per the #326 landing order).

- packages/git-sync: src (lib converter + engine) + test corpus + configs.
- Remove develop's dead committed packages/git-sync/build/; gitignore it
  (built in CI/Docker via pnpm build, never committed — no src/build drift).
- pnpm-lock.yaml: add the @docmost/git-sync importer (a missing workspace
  package in the lock is a CI blocker). `pnpm install --frozen-lockfile` passes.
- NO server integration / loader / Dockerfile runtime changes (those come with
  #119 at step 6).

Verified: tsc clean; vitest 711 passed | 1 expected-fail, 0 failures, 0 type
errors; pnpm --frozen-lockfile EXIT 0; apps/server has no git-sync import.
