v3.11.5 - Recording Clock Hotfix

P0. Emergency fix for the root cause found in #319: per-speaker audio tracks have never shared a session clock, so every multi-speaker recording ever produced has a scrambled timeline. Small, self-contained, testable in CI, and it must ship with a silence strategy or it is a regression. See docs/.internal/session-lifecycle-review-2026-08.md section 7.
