Claim PRIME session lock. This makes the current session the exclusive recipient of:

• Incoming Signal messages (via signal-bridge)
• TTS playback rights
• Any other inbound comms routing

Steps:

1. Call whoami_info to get your session ID.
2. Write that session ID to ~/.local/state/opencode/prime.lock (create parent dirs if needed).
3. Confirm: "PRIME locked to session {id}"

This always overwrites — no contention check, no confirmation needed. The current session becomes PRIME immediately.
