pakrym-oai cf4c8cab7c Track collaboration mode instructions in world state (#33876)
## What changed

- Model collaboration mode as a world-state section whose persisted snapshot is
  the active mode.
- Emit collaboration instructions when the mode changes, while ignoring
  instruction text changes within the same mode.
- Restore persisted collaboration instructions when they are missing from
  retained history, including after a fork.

## Testing

- Add snapshot coverage for initial, unchanged, changed, and unknown mode state.
- Cover retained-history restoration and same-mode instruction changes.
