This commit batches the pending workspace updates that were coupled in practice: extension reliability fixes, ghost cursor persistence across MPA navigations, timeout tuning, and aligned docs/versioning updates so behavior and guidance stay in sync.
Key updates:\n- extension: add MV3 keepalive via chrome.alarms, add alarms permission, and bump extension changelog/version to 0.0.73 to reduce silent relay disconnects while idle\n- playwriter runtime: raise default action timeout to 60s while keeping navigation timeout separate; increase relay /version fetch timeout to 2000ms\n- recording + cursor: add persistent cursor init scripts with Page.addScriptToEvaluateOnNewDocument, remove init script on teardown, and ensure cursor enablement before applying mouse actions\n- demo video defaults: use 0.5s side buffer (1s total) and default idle speed 6x for createDemoVideo/computeIdleSections\n- tests/docs: keep click-error tests deterministic with explicit 5000ms per-click timeout, remove outdated click-timeout section from skill mistakes, and update package/changelog entries
Route Runtime.enable/disable through the incoming child sessionId instead of always using the tab root session so OOPIF iframe targets receive execution contexts reliably. Add a focused relay regression test for empty-src cross-origin iframe attach flow and update extension version/changelog for release tracking.
- Server rejects new extension (code 4002) if existing has active tabs
- Idle extensions (no tabs) can still be replaced
- Extension properly enters polling mode when rejected during handshake
- /extension/status now returns activeTargets count for smarter reconnection
