Fixes multiple blocking issues identified in PR review:

1. Replaced optimistic verify_worker_started() that always returned True
   with hardened verification using JSON-parsed session state checks,
   dict key lookup (not raw string matching), and 3 retries with
   exponential backoff (2s, 4s, 8s). Returns distinct states: "active",
   "initializing", and "failed" to prevent ghost worker accumulation.

2. Replaced bare except: pass with specific except Exception handling
   to follow fail-fast principles and prevent swallowed errors.

3. Added adaptive main loop sleep: 2s base, increases to 5s when
   >80% capacity to reduce API call density under load.

4. Updated retry delays from fixed 2s to 4s exponential backoff
   for faster transient-failure recovery without retry storms.

5. Removed dated Performance Optimizations section from top of
   agent definition (anti-pattern) and moved it to proper position
   after compliance section.

6. Removed "No Throttling" resource monitoring comment.

All qualitative review blockers addressed.

Details 
- Reduce main dispatch loop sleep from 10s to 2s (5x faster cycles)
- Simplify worker verification from 5 retries to 1 quick check
- Remove unnecessary delays between dispatch operations
- Reduce retry delays from 15s to 2s for faster recovery
- Reduce idle sleep from 60s to 10s for quicker response
- Add optimistic verification to trust dispatch success

These changes enable the orchestrator to scale from 1-4 workers to the
full 32 workers within seconds instead of minutes, dramatically increasing
system throughput and allowing autonomous unblocking of CI failures.
