fix(bridge): stall-based approval detection + known issues from deep debugging

- IDLE→stall detection: RUNNING+delta=0 for 6 polls (30s)
- lastModifiedTime-based thinking filter (partial)
- ResolveOutstandingSteps confirmed CANCELS steps (removed)
- HandleCascadeUserInteraction always socket hang up (removed)
- VS Code accept commands: silent success, no effect
- Hybrid approval: focus+all commands sequential, no break
- logToFile: console.log backup added
- Known issues: 4 critical findings documented
- better-antigravity reference added for future research

+# Discord Bridge 승인 로직 정밀 디버깅

+- **시간**: 2026-03-08 11:30~14:35
+
+## 결정 사항
+
+- IDLE 기반 감지 → stall 기반 (RUNNING+delta=0) 전환
+- `ResolveOutstandingSteps` → step cancel 발견 → 제거
+- VS Code accept commands → 무효과 (webview focus 의존) → OS 레벨 필요
+
+## 미완료
+
+- Accept 프로그래밍: OS 레벨 UI Automation 접근 필요
+- Thinking/생성 중 false stall: 추가 discriminator 필요
