Add support for signaling phase completion when a polecat needs to wait
on a gate before continuing. The --phase-complete flag with --gate ID
allows polecats to hand off control while awaiting external conditions.
Changes:
- done.go: Add --phase-complete and --gate flags, PHASE_COMPLETE exit type
- protocol.go: Add Gate field to PolecatDonePayload
- handlers.go: Handle PHASE_COMPLETE by recycling session (keep worktree)
- beads.go: Add AddGateWaiter method for gate registration
This enables multi-phase molecule workflows with async coordination (bd-gxb4)

Add protocol message parsing and handlers for polecat→witness communication:
- POLECAT_DONE: Parse completion messages, create cleanup wisps
- HELP: Parse help requests, assess if Witness can help or escalate to Mayor
- MERGED: Parse refinery merge confirmations
- LIFECYCLE:Shutdown: Handle daemon-triggered shutdowns
- SWARM_START: Parse batch work initialization
Files added:
- internal/witness/protocol.go: Message classification and parsing
- internal/witness/handlers.go: Handler implementations with wisp/mail integration
- internal/witness/protocol_test.go: Unit tests for all parsing functions
