fix: Remove PID/tmux state inference (gt-psuw7)

ZFC compliance: daemon becomes pure transport layer, trusting agent beads.

Changes:
- refinery Status(): Simply returns loaded state, no PID/tmux reconciliation
- witness Status(): Simply returns loaded state, no PID inference
- daemon ensureDeaconRunning(): Trusts agent bead state, no tmux fallback
- daemon pokeDeacon(): Trusts agent bead state, no HasSession check

Removed:
- 78 lines of state inference code (PID checks, tmux session parsing)
- "Reconciliation" logic that overwrote agent-reported state

Note: Timeout fallback for dead agents is gt-2hzl4 (separate issue).
