The artifact sidecar already records a version event log (create/edit/read/delete with timestamps + sessionId). Surface it in the panel:
- A version timeline for the open artifact (who/when, event type).
- Restore a previous version.
Restore needs content snapshots — write each version's content into <project>/.youcoded/content/<versionId> at write time (under our control, not CC's transcript, per the v1 PITFALLS note). Deferred from the 2026-06 artifact-panel UX pass.
