docs(reports): TRACK_COMPLETION_result_migration_app_controller_20260618 (Phase 6 final)

End-of-track report covering all 6 phases:
- Phase 1-5: completed (regression fix, 32 broad catches, 4 rethrows, cold_start_ts)
- Phase 6: 30 INTERNAL_SILENT_SWALLOW sites migrated to proper Result[T]
  propagation with real drain points (Pattern 3 os._exit, stderr +
  instance state, Pattern 4 telemetry, Pattern 5 bounded retry).
  No logging.debug in except bodies. Audit count: 30 -> 0.

State, metadata, and plan updated to reflect completion. Track is
ready for user review and merge to master.

Focus: replace every `except ...: logging.debug(...); <local side effect>` body with proper `Result[T]` propagation. The 8 sites that Phase 3 "migrated" with `logging.debug` did not satisfy the convention (per `error_handling.md:530` — logging is NOT a drain). Phase 6 fixes all 28 sites with real `Result` propagation + real drain points.
