feat(02-03): retry-aware failure escalation pipeline

- Add MAX_RETRY_ATTEMPTS (2) and RETRY_COOLDOWN_MS (30s) constants
- Replace immediate escalation with retry-then-escalate logic
- Escalation chain: retry same agent -> manager -> CEO -> user notification
- Reset retry count on successful task completion
- Update Reassign on run failure automation rule with afterRetryExhaustion condition
- Add comprehensive unit tests for escalation state machine (11 tests)
