[Phase L3-9 + 버그] AX Agent 오류 수정 + 런처 미니 위젯 4종 구현

AX Agent 오류 수정:
- AgentSettingsPanel.xaml에 <UserControl.Resources> 추가
- ToggleSwitch 스타일 자체 정의 (SettingsWindow 리소스 미접근 문제 해결)
- 원인: XamlParseException — 'ToggleSwitch' 리소스 찾을 수 없음 (CS 로그 확인)

PerformanceMonitorService.cs (신규, 138줄):
- GetSystemTimes P/Invoke → CPU% (이전/현재 샘플 델타 계산)
- GlobalMemoryStatusEx P/Invoke → RAM% + "6.1/16GB" 형식 텍스트
- DriveInfo → C: 드라이브 사용률/용량 텍스트
- 2초 폴링, StartPolling/StopPolling 제어

PomodoroService.cs (신규, 179줄):
- 집중(25분)/휴식(5분) 타이머, 상태: Idle/Focus/Break
- pomodoro.json 영속성 (경과 시간 자동 보정)
- StateChanged 이벤트 → 위젯 실시간 갱신

ServerStatusService.cs (신규, 124줄):
- Ollama(/api/version), LLM API, 첫 번째 MCP 서버 15초 주기 핑
- HttpClient 1.5초 타임아웃, StatusChanged 이벤트

PomoHandler.cs (신규, 130줄):
- pomo prefix: 상태보기/start/break/stop/reset
- PomodoroService 직접 연동

LauncherViewModel.Widgets.cs (신규, 81줄):
- Widget_PerfText, Widget_PomoText, Widget_PomoRunning
- Widget_NoteText, Widget_OllamaOnline, Widget_LlmOnline, Widget_McpOnline
- UpdateWidgets() — 5틱마다 메모 건수 갱신 (파일 I/O 최소화)

LauncherWindow.Widgets.cs (신규, 143줄):
- IsVisibleChanged 이벤트로 위젯 자동 시작/중지
- DispatcherTimer 1초마다 UpdateWidgets + 서버 상태 dot 색상 직접 갱신
- 위젯 클릭 → 해당 prefix 자동 입력 (perf→info, pomo→pomo, note→note, server→port)

LauncherWindow.xaml:
- RowDefinition 6개 → 7개
- Row 6: 위젯 바 (시스템모니터/뽀모도로/메모/서버 4열)

빌드: 경고 0, 오류 0
