for lifecycle mail targets:
- internal/cmd/handoff.go: getManager() returns deacon/ for Mayor/Witness
- internal/daemon/lifecycle.go: ProcessLifecycleRequests uses deacon/ inbox
- docs/architecture.md: update all references in lifecycle docs
- scripts/mayor-respawn-daemon.sh: use BD_IDENTITY=deacon for mail commands
