feat(bot,bridge): P1 !auto 토글 자동승인 + P2 BridgeTransport 추상화 #task-304 #task-305

P1: !auto 토글 (bot.py + extension.ts)
- auto_approve_projects set으로 프로젝트별 상태 관리
- !auto → on/off 토글, pending 자동 승인 + 🤖 자동 승인됨 embed
- Extension step_probe에서 autoApproveEnabled 시 직접 tryApprovalStrategies

P2: BridgeTransport 추상화 (bridge.py)
- BridgeTransport ABC + LocalTransport (기존 동작 100% 호환)
- RemoteTransport 스켈레톤 (multi-PC 대비)
- config.py BOT_MODE/REMOTE_BRIDGE_URL, main.py transport 주입

+또는:
+```powershell
+C:\ProgramData\miniforge3\envs\gravity_control\python.exe main.py

+```powershell
+cd extension
+cmd /c npm run compile
+cmd /c npx vsce package
+# 생성된 .vsix 파일을 VS Code에서 설치
+```
