Summary:
- Add explicit sessions cleanup --fix-dm-scope handling for stale direct-DM rows after session.dmScope returns to main.
- Preserve removed-row transcripts as deleted archives and expose the option through CLI, Gateway RPC, protocol schema, generated Swift mirrors, docs, tests, and changelog.
- Fixes#47561 and #45554.
