Cross-Layer Integration Tests: Governance Plugin <-> Hardbound Team.

These tests validate that the governance plugin (claude-code-plugin/governance/)
and the Hardbound team system (hardbound/) share state correctly through
the common SQLite ledger.

Integration seams tested:
1. Unified audit chain (plugin actions visible in team ledger)
2. Entity trust flows into team member capabilities
3. Heartbeat ledger integrates with team metabolic state
4. R6 requests from plugin match team policy enforcement
5. Presence tracking signals team health
