Implement Boot: daemon entry point dog for Deacon triage (gt-rwd5j)
Boot is a watchdog that the daemon pokes instead of Deacon directly, centralizing the 'when to wake Deacon' decision in an agent that can reason about context. Key changes: - Add internal/boot package with marker file and status tracking - Add gt boot commands: status, spawn, triage - Add mol-boot-triage formula for Boot's triage cycle - Modify daemon to call ensureBootRunning instead of ensureDeaconRunning - Add tmux.IsAvailable() for degraded mode detection - Add boot.md.tmpl role template Boot lifecycle: 1. Daemon tick spawns Boot (fresh each time) 2. Boot runs triage: observe, decide, act 3. Boot cleans stale handoffs from Deacon inbox 4. Boot exits (or handoffs in non-degraded mode) In degraded mode (no tmux), Boot runs mechanical triage directly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Boot is a special dog that runs fresh on each daemon tick. It observes
|
||||
the system state and decides whether to start/wake/nudge/interrupt the
|
||||
Deacon, or do nothing. This centralizes the "when to wake" decision in
|
||||
an agent that can reason about it.
|
||||
|
||||
Boot lifecycle:
|
||||
1. Daemon tick spawns Boot (fresh each time)
|
||||
2. Boot runs triage: observe, decide, act
|
||||
3. Boot cleans inbox (discards stale handoffs)
|
||||
4. Boot exits (or handoffs in non-degraded mode)

|

This is for degraded mode operation when tmux is unavailable.
|

It performs basic observation and takes conservative action:

- If Deacon is not running: start it
