1. credential_pool flows through resolve_turn_route (no-route and fallback paths)
2. CLI _resolve_turn_agent_config passes credential_pool to primary dict
3. Gateway _resolve_turn_agent_config passes credential_pool to primary dict
4. Eager fallback deferred when credential pool has credentials
5. Eager fallback fires when no credential pool exists
6. Full 429 rotation cycle: retry-same → rotate → exhaust → fallback
