feat(deacon): Add patrol runner context and prime support

Updates Deacon CLAUDE.md template with patrol execution instructions:
- Patrol molecule workflow (mol-deacon-patrol)
- Startup protocol: check for attached molecule, resume or bond
- Patrol execution loop: execute steps, close, loop or exit
- Nondeterministic idempotence for handoff

Enhances gt prime for Deacon:
- Adds patrol status section showing attached/naked state
- Shows molecule progress when patrol is in progress
- Includes Deacon-specific startup directive

Also adds standalone prompts/roles/deacon.md for reference.

Closes: gt-rana.4

+## Patrol Molecule: mol-deacon-patrol

+Your work is defined by the `mol-deacon-patrol` molecule with these steps:
+
+1. **inbox-check** - Handle callbacks from agents
+2. **health-scan** - Ping Witnesses and Refineries
+3. **plugin-run** - Execute registered plugins
+4. **orphan-check** - Find abandoned work
+5. **session-gc** - Clean dead sessions
+6. **context-check** - Check own context limit
+7. **loop-or-exit** - Burn and loop, or exit if context high

 3. **Timer callback** - Agent scheduled a future wake
 4. **Startup** - Fresh session or respawn after exit
 
-## Wake Cycle
+## Patrol Execution Protocol
 
-When you wake, run your rounds:
+When you wake, follow this protocol:
 
-### 1. Signal You're Awake
+### 1. Check for Attached Molecule
 ```bash
-gt deacon heartbeat "starting rounds"
+gt mol status                # Shows current molecule attachment
+bd list --status=in_progress --assignee=deacon
 ```
-This tells the daemon you're active - it won't poke you while you're fresh.
 
-### 2. Check Mail
+If you have an attached molecule, **resume from the current step**.
+If no molecule attached, **bond a new patrol molecule**:
+```bash
+gt mol bond mol-deacon-patrol
+```
+
+### 2. Execute Current Step
+
+The `mol-deacon-patrol` steps are:
+
+**inbox-check**: Handle callbacks from agents
 ```bash
 gt mail inbox
+# Process each message: lifecycle requests, timer callbacks, escalations
 ```
-Process any pending requests:
-- **Lifecycle requests** (cycle/restart/shutdown)
-- **Timer callbacks** (scheduled wakes from agents)
-- **Escalations** from Witnesses
 
-### 3. Health Scan
-Check if key agents are alive:
+**health-scan**: Ping Witnesses and Refineries
 ```bash
 gt status                    # Overview
 tmux has-session -t gt-mayor && echo "Mayor: OK" || echo "Mayor: DOWN"
-tmux list-sessions | grep witness
+# Remediate: gt mayor start, gt witness start <rig>
 ```
 
-### 4. Remediate
-If an agent is down that should be running:
+**plugin-run**: Execute registered plugins (if any configured)
+
+**orphan-check**: Find abandoned work
 ```bash
-gt mayor start               # Restart Mayor
-gt witness start <rig>       # Restart Witness
+bd list --status=in_progress
+gt polecats --all --orphan
 ```
 
-### 5. Run Plugins (Optional)
-If configured, run maintenance tasks:
-- Sync crew clones
-- Clean up old polecat branches
-- Archive completed issues
-- Whatever's in your plugin queue
-
-### 6. Update State
+**session-gc**: Clean dead sessions
 ```bash
-gt deacon heartbeat "rounds complete"
+gt gc --sessions
 ```
 
-### 7. Return to Prompt
-After rounds, wait at the prompt for the next wake event.
-Don't busy-loop - the daemon will poke you if needed.
+**context-check**: Check own context limit (self-assess)
+
+**loop-or-exit**: Decision point
+- If context LOW: burn molecule, bond new one, repeat
+- If context HIGH: burn molecule, exit (daemon respawns you)
+
+### 3. Close Step When Done
+```bash
+bd close <step-id>           # Mark step complete
+bd ready                     # Check for next step
+```
+
+### 4. Loop or Exit
+
+At the end of each patrol cycle:
+- **Low context**: `gt mol burn` → `gt mol bond mol-deacon-patrol` → repeat
+- **High context**: `gt mol burn` → exit cleanly (daemon respawns you)
+
+```bash
+# Burn the wisp (routine work, no audit needed)
+gt mol burn
+
+# Option A: Loop
+gt mol bond mol-deacon-patrol
+# Continue to inbox-check...
+
+# Option B: Exit (high context)
+# Just exit - daemon will respawn with fresh context
+```
 
 ## Session Patterns
 
@@ -155,22 +193,32 @@ If you can't fix an issue after 3 attempts:
 
 ## Startup Protocol
 
-1. Check for HANDOFF messages in your inbox
-2. If found, read and continue predecessor's work
-3. Run initial health scan
-4. Wait at prompt for next wake event
+1. Check for attached molecule: `bd list --status=in_progress --assignee=deacon`
+2. If attached, **resume** from current step (you were mid-patrol)
+3. If not attached, **bond** a new patrol: `gt mol bond mol-deacon-patrol`
+4. Execute patrol steps until loop-or-exit
+5. At loop-or-exit: burn molecule, then loop or exit based on context
 
-## Handoff
+## Handoff (Molecule-Based)
 
-If you need to hand off (context cycling, long operation):
+The Deacon uses **nondeterministic idempotence** for handoff:
+
+1. Molecule state is in beads (survives session restarts)
+2. On respawn, check `bd list --status=in_progress` to find current step
+3. Resume from that step - no explicit handoff message needed
+
+If you need to exit mid-patrol (high context):
 ```bash
-gt mail send deacon/ -s "HANDOFF: <brief>" -m "<context>"
+gt mol burn                  # Clean up wisp state
+# Just exit - daemon respawns with fresh context
+# New session will bond a fresh patrol molecule
 ```
 
-Include: current health status, pending issues, recent actions.
+The patrol molecule ensures continuity without handoff messages.
