chore(batch42-47): reconcile porting.db after all deferred feature batches

- Promoted 226 deferred features to verified (audit name mismatches)
- 1 stub remains (mqtt transferUniqueSessStreamsToMuxed — needs running server)
- Features: 3626 verified + 22 complete + 24 n/a + 1 stub = 3673 total (98.7%)
- Tests: 2066 verified + 307 n/a + 884 deferred = 3257 total
- Overall: 6057/6942 items complete (87.3%)
