Midnight Glass v2 전면 재설계 + refactor-wave 대규모 코드 품질 정리. 기능 추가보다 시각·구조 개선 중심.

### Added
- **Midnight Glass v2 전면 리디자인**: 미드나이트 네이비 + 글래스모피즘 카드(헤어라인 그라디언트 + 앰비언트 글로우) + 시안→블루→퍼플→마젠타 그라디언트. 6종 테마(dark/light/nord/solarized/catppuccin/dracula) 전환. 보더리스 UI + 커스텀 TitleBar. Pretendard Variable 폰트 오프라인 번들.
- **TiltCard DS**: 커서 추종 3D 틸트 + 스페큘러 빛 반사 (reduced-motion 완전 존중)
- **GradientWave / StatRing DS** 신규 (기존 CrtDisplay WebGL 오실로스코프를 그라디언트 스펙트럼 웨이브로 교체)
- **실시간 부분 전사**: 받아쓰기 홀드 중 RecordingTip에 interim 전사 표시
- **Windows 자동 업데이트**: electron-updater + GitLab Generic Registry feed (4시간 주기, 재시작 다이얼로그)
- **멀티플랫폼 배포**: macOS arm64(ad-hoc 서명) + Windows 동시 릴리스. GitLab Package Registry(버전별+latest) + Release 자동 생성
- **번들 Ollama v0.32.1**: 온보딩 gemma4:e4b pull 412 실패 해소, GPU 런타임 가지치기로 ~1GB→119MB 슬림화
- **gpt-realtime-2.1 라이브 음성 대화** (Premium 백엔드, OpenAI Realtime) — 로컬 파이프라인 자동 fallback
- **Whisper large-v3-turbo 기본 STT**: 6배 빠름, 사이드카 백그라운드 다운로드 API

### Fixed
- **한국어 날짜 "TODAY"/"YESTERDAY" 표시 버그** — `date.today/yesterday` 중복 정의(JSON last-wins) 해소
- **팝업/렌더러 색상 충돌** — 팝업이 v1 주황(`#f25b29`)으로 렌더되던 것을 파랑(`#3b82f6`)으로 SSOT 정합
- **받아쓰기 파이프라인 4버그**: press 액션이 STT 초기화를 await하며 큐 점유→release 지연/유령 세션; 사이드카 crash 루프; RecordingTip hide 타이머 leak; 빈 STT 가드
- **온보딩 무진행 구간 UX**: verifying(모델 검증) 단계 피드백 + 중복 실행 가드
- **마이크 테스트 조기 종료**: 초기 `level:0`을 종료 신호로 오인하던 버그
- **트레이 아이콘 빈 이미지** 버그

### Changed
- **`accent.amber` → `accent.main` 전면 통일** (162건, deprecated 별칭 2곳 제거) — desktop/web/admin/mobile/ui-native 전역. 6 테마 일관.
- **IPC 채널 SSOT 일원화**: `ipc-channels.ts`에 9 그룹/키 추가(INSTRUCTION, POPUP_*, CLIPBOARD, APP 등), 하드코딩 채널 문자열 제거, `ipcSuccess/ipcError` 헬퍼 통일, `catch(error)` 패턴 32건
- **AppConfig 타입 강화**: 7개 누락 키 추가, `as never` 16건 제거, dynamic `require` → static import
- **팝업 i18n**: 4종 팝업(command/history/result/recording-tip) 한국어/영어 하드코딩 → `t()` 키 주입 (`popup.*` 17키)
- **매직 리터럴 토큰화**: 인라인 fontSize/fontWeight/borderRadius → `d3roTypo`/`d3roRadius` 토큰 (렌더러 전역)

### Removed
- DS 미사용 3종: **MetalDial, ButtonGroup, CrtDisplay** (barrel export 포함)
- **미사용 의존성 8종**: `@mui/icons-material`, `@d3ro/api-client`, `fluent-ffmpeg`(+`@types`), `pdf-parse`, `node-record-lpcm16`(+`.d.ts`), `electron-audio-loopback`, `@electron-toolkit/preload`
- **i18n 고아 키 967건** (12 locale) — camelCase license.feature 15키 등 동적 참조는 P1 재검증으로 보존
- `services/index.ts` 데드 레지스트리, `electron-builder.yml` Linux 섹션

### Internal
- **refactor-wave Wave 1+2**: 정책(`docs/REFACTOR_POLICY.md`) 수립 → 공격적 감사(106건) → 9 워크스트림 병렬 → 분리 커밋 9개 + 메타 2. 공유 패키지 토큰 SSOT, IPC/타입 정합, 데드코드 대량 제거. 보고서 `docs/REFACTOR_WAVE1_REPORT.md`·`WAVE2_REPORT.md`.
