Abiba (pi) 33453b8204 feat(zulip): v3 resilience rewrite — circuit breaker, retry, watchdog, model fix
Root cause: Workers hung because default model was DeepSeek v4-pro (reasoning
model that produces empty content with normal token limits). pi RPC workers
waited forever for content that never arrived.

Changes:
- Circuit breaker (CLOSED→OPEN→HALF_OPEN) around Zulip API calls
- Retry with exponential backoff + jitter for transient errors
- Queue lifecycle management (idle_queue_timeout, auto re-register on BAD_EVENT_QUEUE_ID)
- External supervisor watchdog (restarts router after 3 health check failures)
- Busy worker timeout (SIGKILL after 5 min + error DM)
- PM2 hardening (max_restarts=100, max_memory_restart=500M)
- Crash handlers (uncaughtException + unhandledRejection → reconnect, not die)
- Fixed default model: deepseek-v4-pro → syslog-harness/syslog-auto
- Enhanced health endpoint with circuit breaker stats

Architecture: Research-backed from Zulip event system docs + Node.js resilience
patterns. Inline circuit breaker (no dependency). Separate watchdog process (Hermes pattern).

Verified: Circuit breaker trips on outage, recovers gracefully. End-to-end DM
processed in 4 seconds. Watchdog monitoring every 30s.

Abiba (pi) 0112c5bba7 feat: /zulip-test command + standardized health schema v1
- Added /zulip-test self-test command (7 checks: queue, identity,
  @all-bots, health, poll loop, echo prevention, API send)
- Standardized health endpoint to zulip-health/v1 schema
  (nested zulip{} object, checks{} map, platform/agent metadata)
- Saved pi extension source to pi-zulip-extension/extension-src/
  (with all fixes: dynamic @all-bots, health sync, logging)
- Added extension src to repo for deployment tracking
- Updated vault with final contract status report
