Prevents rapid retry attempts when token refresh hits KIS API's 1-per-minute rate limit (EGW00133: 접근토큰 발급 잠시 후 다시 시도하세요). Changes: - src/broker/kis_api.py:58-61 - Add cooldown tracking variables - src/broker/kis_api.py:102-111 - Enforce 60s cooldown between refresh attempts - tests/test_broker.py - Add cooldown behavior tests Before: - Token refresh fails with EGW00133 - Every API call triggers another refresh attempt - Cascading failures, system unusable After: - Token refresh fails with EGW00133 (first attempt) - Subsequent attempts blocked for 60s with clear error - System knows to wait, prevents cascading failures Test Results: - All 285 tests pass - New tests verify cooldown behavior - Existing token management tests still pass Implementation Details: - Cooldown starts on refresh attempt (not just failures) - Clear error message tells caller how long to wait - Compatible with existing token expiry + locking logic Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
