fix: KeyboardInterrupt safety, corrupted entry repair, disabled run guard

- Catch BaseException (not just Exception) in update swap/registry to
  handle KeyboardInterrupt and restore backup on Ctrl+C
- Preserve installed_at (or set fresh one) when repairing corrupted
  non-dict registry entries in WorkflowRegistry.update()
- Block 'workflow run' for disabled workflows with clear error message
  and re-enable hint
