Synced from monorepo

Changes:
- Persist submitter identity for /feedback
- Let custom models use rotating tokens from named auth providers
- Template stale tool/param name literals in server-native descriptions
- Minimal mode commits thinking in full, lookups as one-liners
- Tighten durable append internals
- Nudge model to end turn on no-op bash commands
- Per-fetch signing nonce in the managed-config envelope, with a server-side replay probe
- Include working tree in startup status
