feat(handoff): route crew lifecycle requests to deacon

Crew workers now use deacon for lifecycle management instead of
requiring manual session termination. When a crew worker runs
'gt handoff', it sends a lifecycle request to the deacon which
handles session kill/restart like it does for Mayor and Witness.

Changes:
- Route crew manager to deacon/ instead of "human"
- Add getCrewIdentity() to extract <rig>-crew-<name> from session
- Include full crew identity in LIFECYCLE subject for daemon parsing
- Remove special case that skipped lifecycle flow for crew

Also fixes pre-existing test failures in daemon/lifecycle_test.go
where BeadsMessage field names were out of sync with the struct.
