- drift-detect.ts: every-N-edits + beforeunload check via kicadSave* (no save-hook), reports drift
- WasmTool: start drift detection after collab; return collab handle; stop on cleanup
- fix uuid-less docs (pl_editor): use ydocHasState in maybeConnectDocSession + seed() so a 2nd tab materializes the room instead of refetching the stale file
- api: reportDrift + reportDriftBeacon (sendBeacon/keepalive)
- global.d.ts: FS.unlink
- bump web/pcbjam-shared pointer
