fix(agents): pin post-discovered session ids on a verified completed; agy never takes another workspace's or session's conversation (Issue #40)

- BaseAgentAdapter: id_lifecycle (pre_assigned: claude, grok / post_discovered)
  and capture_active_session_id - exactly one verified candidate newer than the
  session that no other row records, else a reason (no-candidate, ambiguous, ...).
- agy: verify_artifact (discover) rejects an id last_conversations.json maps to
  another workspace and always excludes ids other rows record (a cache hit no
  longer bypasses it). capture uses the cache only as a proposal: the
  conversation's presence lock or DB must be held by the row's pane process or
  a descendant (lsof/ps); anything unprovable is not pinned.
- lib_py/agents/autopin.py: handle_completed, run by the side that verified the
  job's completed - the delegate-job wrapper (direct), create --onboard and the
  loop's wait_for_job (recovery, as a subprocess: G9). Local herdr jobs only;
  one (job, dispatch token, attempt) is handled once (job-scoped flock + marker
  in the job dir); writes go through atomic_dump_yaml; a pin records
  session_id_source=discovered / session_id_verified=true; a failure leaves the
  reason on the row and never changes the job's result.
- reconcile.sh drift C for agy, hermes, opencode and codex calls the same
  capture (the agy *.db glob is gone); _pin_and_verify_resume uses pin_row.
- Tests: tests/test_issue40_auto_pin.py; issue64 :407 now expects False; the
  static reconcile-source checks follow the move to the adapters; the two tier2
  drift-C component tests create with --no-onboard (onboarding now pins).
