"""v0.3 PR #1 — interactive session persistence tests.

5 scenarios from the plan:
1. New session via POST /api/sessions → row + first message persists
2. Same session re-listed (resume picker) → still active + history visible
3. `mydeepagent sessions list` returns recent sessions in last-activity order
4. resolve_session_id accepts 6+ char prefix uniquely; rejects ambiguity
5. ended sessions reject further POST /messages
