Consolidate Claude settings management

Settings creation was scattered across multiple places (createPatrolHooks,
ensurePatrolHooks, inline code). Now unified via claude.EnsureSettingsForRole().

Changes:
- Add "deacon" to autonomous roles in claude/settings.go
- Remove ensurePatrolHooks() from cmd/deacon.go, use EnsureSettingsForRole
- Remove createPatrolHooks() from rig/manager.go (no longer needed at rig add)
- Add EnsureSettingsForRole call in crew_lifecycle.go
- Add doctor check for stale/missing Claude settings files
- Wire up claude-settings check in cmd/doctor.go
