Define the Deacon patrol molecule in builtin_molecules.go with 7 steps:
1. inbox-check - Handle callbacks from agents
2. health-scan - Ping Witnesses and Refineries
3. plugin-run - Execute registered plugins
4. orphan-check - Find abandoned work (uses wisp terminology)
5. session-gc - Clean dead sessions and wisp artifacts
6. context-check - Check own context limit
7. loop-or-exit - Burn and let daemon respawn, or exit if context high
Added DeaconPatrolMolecule() to BuiltinMolecules() list and added
corresponding test in builtin_molecules_test.go.
