Phase 4 구현: Ollama LLM 연동 (다듬기, 번역, 스트리밍)

- LocalLLMService: Ollama REST API, 스트리밍 NDJSON 파싱, 5초 가용성 폴링
- 시스템 프롬프트: refine/translate/summarize/grammar/expand/custom 6개 액션
- VoiceModeService: 전사→LLM 후처리→텍스트 삽입, LLM 실패 시 원본 폴백
- LLM IPC 핸들러: status/models/process/cancel/serverUrl 8개
- StatusBar: Ollama 연결 상태 + 활성 모델 표시
- Preload: llm API 섹션 추가
- Bootstrap: llm-polling 초기화 단계 추가
