fix(doctor): require --restart-sessions flag to cycle patrol sessions (gt-j44ri)

Previously `gt doctor --fix` would automatically kill and restart patrol
sessions when fixing stale settings.json files. This was disruptive as it
interrupted work without explicit consent.

Now session cycling only happens when `--restart-sessions` is explicitly
passed along with `--fix`. Without the flag, settings files are updated
but running sessions are left alone.
