fix: pm2-self-heal — self-process guard, never restart abiba-zulip

- Added --no-color flag to all PM2 commands
- Self-process guard: abiba-zulip is READ-ONLY, never restarted
- Corrected column indices (PID=6, restarts=8, status=9)
- Added pm2-self-heal.sh shell script implementation

Monitors critical PM2 processes (abiba-zulip, abiba-telegram) and
auto-restarts any that are stopped or errored. Logs every action to
the knowledge graph and alerts the owner via Zulip DM on failures.
CRITICAL: Never restart abiba-zulip — it runs this contract.

## Execution
1. **Check PM2 status** — Run `pm2 status` and parse the table
2. **For each critical process** (abiba-zulip, abiba-telegram):
1. **Check PM2 status** — Run `pm2 status --no-color` and parse the table (5th data column = PID, 8th = restarts, 9th = status)
2. **Check abiba-telegram**:
- If status is "online" → pass
- If status is "stopped" or "errored" → apply Rule 1
- If restarts > 5 → apply Rule 2
3. **Log results** — Create `[LEARN]` node in knowledge graph for any actions taken
4. **Alert owner** — Send Zulip DM if escalation needed
5. **Wait 5 min** → repeat from step 1
- If restarts > 5 → alert owner
3. **Check abiba-zulip** (self-process, read-only):
- If status is "online" → pass, log restarts count
- If status is "stopped" or "errored" → **DO NOT RESTART** — alert owner immediately
- If restarts > 5 in last hour → alert owner with full diagnostics
4. **Log results** — Create `[LEARN]` node in knowledge graph for any actions taken
5. **Alert** — Send Zulip DM to owner if escalation needed (do NOT run pm2 commands during alerting)
6. **Wait 5 min** → repeat from step 1
