v0.3.4

Added

• A documented update path + drift detection. New "Updating to a new version" guide for both install routes (README + QUICKSTART §9) — the npm two-step (npm i -g @latest → cmk install per project) and the plugin flow (/plugin update → /reload-plugins → re-bootstrap), with the Windows EBUSY "close Claude Code first" note. A new cmk doctor check (HC-9) flags a project whose scaffold is behind your installed cmk after an update, so the easily-forgotten per-project re-install never goes unnoticed.

Fixed

• Compression now recovers from a transient Haiku failure instead of leaving the session buffer stuck. The lifecycle compression passes (daily distill, weekly curate, the lazy session-start roll) retry once with backoff on a transient timeout / overload, so an intermittent claude --print slowdown no longer strands now.md until the next session. Failures are also now logged with their exit code + reason for diagnosis. (#206)
