v0.10.6

**Major release** — Pack U structural fix for the audio recording pipeline + Pack M chunk-accumulation memory leak fix + Pack H helm chart hardening.

## Highlights

- **Pack M (chunk-leak fix)** — closes the v0.10.5.2 24-min recording crash class. Splice-on-upload + cap=10 across all 3 platforms.
- **Pack U.5 (server-side master finalizer)** — recordings built server-side from chunks already in MinIO. Crash-safe for the first time: SIGKILL'd / OOM'd / evicted bots produce playable masters.
- **Pack U.1-U.4 (audio pipeline unification)** — single `services/audio-pipeline.ts` module driving GMeet (MediaRecorder), Teams (MediaRecorder), Zoom Web (PulseAudio). ~2300 LOC of platform duplication deleted.
- **Pack U.7 (master-path race fix)** — chunk-write defensive guard prevents late-chunk POSTs from stomping the server-built master path.
- **Pack D-3 (audio playback streams from bucket)** — dashboard `<audio src>` binds to MinIO presigned URL with native HTTP Range. Sub-second seek, no full-file pre-download.
- **Pack H (helm chart hardening)** — `maxUnavailable: 0` rolling updates, `replicaCount: 2` for stateless services, `helm upgrade --atomic --wait`. Closes the v0.10.5.2 ship-time outage class.
- **Pack O / Pack T (observability)** — bot stdout structured JSON drained to `meetings.data.bot_logs`; bot resource (cgroup memory + cpu) sampled at 30s and stored on `meetings.data.bot_resources`.
- **Pack FM-274 (hallucination corpus restored)** — three-layer defense: corpus files present, `.gitignore` exception, fail-loud build.
- **Pack C (user-stop classifier)** — DELETE during awaiting_admission → `completed`, not `failed`.
- **#304 (dashboard pagination dedupe)** — closes duplicate-rows class.

## Validation

- 25+ cells real-meeting matrix (compose + helm + lite × gmeet + teams + zoom) — Pack U.7 race fix verified live.
- Audit (categories 1-7): clean. 1 MAJOR (callbacks.py:318) deferred to #306.
- 22 v0.10.6 + 3 Pack U.7 static-grep checks GREEN on all 3 modes.

## Deferred

- #305 — Zoom audio quality lower than GMeet/Teams (PulseAudio signal-chain artifact)
- #306 — callbacks.py:318 broad-except narrow
