Release v0.11.6

[jonbaldie]

Summary

v0.11.5 → persistence fixes on main → v0.11.6

Patch release; empty release marker, matching prior releases. No additional code changes.

• Make FileStore's JSON serialization contract explicit (Architecture: Make FileStore's JSON serialization contract explicit #159).
• Record real full-disk persistence exploration (docs: exploratory testing pass for persistence under a full disk (2026-10-10) #162).
• Handle short writes without acknowledging incomplete items or corrupting later log entries (Short writes on a full PERSIST volume are reported as success and corrupt persist.dat, losing acknowledged items #160, Fix short writes on a full PERSIST volume losing acknowledged items #163).
• Keep Queue state unchanged when a Persist Engine write fails (Enqueue/dequeue return 500 when the persist write fails but have already changed the queue (rejected items delivered, dequeued items lost) #161, Lock the queue when a persist write fails (#161) #164).

Evidence

• Before: v0.11.5 at 8a73d0d; four unreleased commits through bef9aa5.
  After: identical tree to bef9aa5, prepared for v0.11.6.
• Deno 2.7.6: frozen dependency install, production type check and compile passed; 345 local production tests passed, including real OS short-write/restart regressions.
• npm run quality:production passed; messcript dependencies installed with npm ci in this workspace.
• Compiled binary HTTP smoke passed: health, auth, invalid JSON/null/oversize rejection, typed FIFO, non-destructive HEAD, crash replay, graceful shutdown/restart replay.
• Full test suite and both mutation jobs must pass in PR CI before merge. Local Stryker is not installed or lockfile-pinned; the existing CI supplies it without changing this workspace's dependencies.
• No release/deployment workflow is documented. After CI and merge: tag the merge commit and publish a GitHub release. No deployment or binary assets are required by this fallback workflow.

Full Changelog: v0.11.5...v0.11.6

Merge Danger

Door: two-way (release marker only; fix rollbacks require a later release).

Blast Radius: persistence

Included fixes change failure handling on full/unwritable persistence storage; no log-format change.
