Subject: [PATCH] fix(session-projection-cache): drain in-flight writes on
 disposal; sync stale lockfile and generated docs

- Track fire-and-forget durable writes and await them at plugin disposal so
  a late flush can never land after teardown (fixes the ENOTEMPTY cleanup
  race in the disposal test).
- Drop the now-async-less Service.init and flushSoft void operators to keep
  lint clean, and remove the redundant dsh-storage-json devDependency.
- Regenerate the stale pnpm lockfile and the config/persistence/module-graph
  catalogs (with zh mirrors and pairing records) that the per-session cache
  merge left out of sync, and fix the session-projection type-equiv doc
  blocks to match the source.
- Add coverage for the unrelated-log-identity and no-per-session-directory
  (sqlite) cold-read paths.
