Runbooks were a half-built feature that provided no value:
- Only 3 runbooks existed
- AI dynamic remediation already covers the same ground
- Added UI complexity without benefit
Removed:
- runbooks.go and runbooks_test.go
- Handler functions in ai_handlers.go
- Routes in router.go
- Test cases in ai_handlers_test.go
- Auto-fix call in patrol.go
Kept (dead code but harmless):
- Frontend types/API calls (will 404)
- RecordIncidentRunbook function (unused)
Less code = easier to maintain.
