* feat(cli): add skip flags and comprehensive tests for generate-metadata

- Add --skip-scripts, --skip-flows, --skip-apps flags for granular control
- --schema-only now properly skips flows and apps (they only have locks)
- Dynamic "Checking X, Y, Z..." message based on what's being processed
- Show warning when all types are skipped
- Add comprehensive tests for all flags:
  - --dry-run shows stale items without updating
  - --schema-only only processes scripts
  - --skip-scripts, --skip-flows, --skip-apps work correctly
  - skipping all types shows warning
  - 'All metadata up-to-date' when nothing to update
