0.29.0

Harden trace privacy and bounded mutation capture; rotate continuous bundles before writes and retain segments by default. Fix CDP selection cleanup and zero-page reconnect, add persistent profile adoption, idle heartbeats and tab enforcement, preserve queued trigger starts during stop, and make overlay dismissal report failures safely. Export trace rendering/summary tools and document the 0.28 trigger migration and packaged guides.
