fix: 修复 AILogo 噪音、设置页滚动与供应商批量伪内置脏数据

- AILogo: `custom` 名称为合法兜底场景，不再以 console.error 上报；其余未匹配名称降级为 console.warn
- SettingPage/Model: 双栏加 `min-h-0 overflow-y-auto`，让供应商列表与右侧表单各自可滚动
- ProviderService.add_provider: API 创建一律落到 `type='custom'`，并对同名供应商抛 ValueError，避免再产生伪内置行
- CLAUDE.md: 补充 v2.0.0 子系统（RAG/Chat、可选 Nacos+RabbitMQ、i18n、cookie/transcriber 管理器）

 ## Architecture
 
 **Backend** (`backend/`) — FastAPI app, entry point `main.py`:
-- `app/routers/` — API routes: `note.py` (generation), `provider.py`, `model.py`, `config.py`
-- `app/services/` — Business logic: `note.py` (NoteGenerator orchestrates the full pipeline), `task_serial_executor.py` (task queue)
+- `app/routers/` — API routes: `note.py` (generation), `provider.py`, `model.py`, `config.py`, `chat.py` (RAG Q&A on generated notes)
+- `app/services/` — Business logic:
+  - `note.py` — `NoteGenerator` orchestrates the full pipeline (download → transcribe → LLM → notes)
+  - `task_serial_executor.py` — task queue
+  - `chat_service.py` + `chat_tools.py` + `vector_store.py` — RAG-based AI Q&A with Function Calling, indexing transcripts and video metadata
+  - `cookie_manager.py` — per-platform cookie storage; injected into yt-dlp by downloaders (e.g. Bilibili)
+  - `transcriber_config_manager.py` — persisted transcriber settings
+  - `worker_registry.py` — **optional** Nacos registration + heartbeat for distributed worker mode (no-op when `NACOS_SERVER_ADDR` unset)
+- `app/messaging/` — **optional** RabbitMQ producer/consumer publishing task progress/results to `bilinote.task.feedback` exchange. Silently degrades when `RABBITMQ_URL` is unset; always import-safe.
 - `app/downloaders/` — Platform adapters (bilibili, youtube, douyin, kuaishou, local) with shared `base.py` interface
-- `app/transcriber/` — Speech-to-text engines (fast-whisper, groq, bcut, kuaishou, mlx-whisper) with factory in `transcriber_provider.py`
+- `app/transcriber/` — Speech-to-text engines (fast-whisper, groq, bcut, kuaishou, mlx-whisper) with factory in `transcriber_provider.py`. YouTube path prefers existing subtitles and skips audio download when available.
 - `app/gpt/` — LLM integration with factory pattern (`gpt_factory.py`), prompt templates (`prompt.py`, `prompt_builder.py`), and `request_chunker.py` for long transcripts
 - `app/db/` — SQLite + SQLAlchemy: DAO pattern (`provider_dao.py`, `model_dao.py`, `video_task_dao.py`), models in `models/`
-- `app/utils/` — `response.py` (ResponseWrapper for consistent JSON), `video_helper.py` (screenshots via FFmpeg), `export.py` (PDF/DOCX)
+- `app/utils/` — `response.py` (ResponseWrapper for consistent JSON), `video_helper.py` (screenshots via FFmpeg), `export.py` (PDF/DOCX), `ppt_generator.py`, `minio_client.py`
+- `app/i18n/` — backend localization
 - `events/` (root level) — Blinker signal system for post-processing (e.g., temp file cleanup after transcription)
 
 **Frontend** (`BillNote_frontend/src/`) — React 19 + Vite + Tailwind + shadcn/ui:
 - `pages/HomePage/` — Main note generation UI: `NoteForm.tsx` (input), `MarkdownViewer.tsx` (preview), `MarkmapComponent.tsx` (mind map)
 - `pages/SettingPage/` — LLM provider management, system monitoring, transcriber config
-- `store/` — Zustand stores: `taskStore`, `modelStore`, `configStore`, `providerStore`
+- `store/` — Zustand stores: `taskStore`, `modelStore`, `configStore`, `providerStore`. Persists to IndexedDB.
 - `services/` — Axios API clients matching backend routes
 - `hooks/useTaskPolling.ts` — Polls task status every 3 seconds
 - `components/ui/` — shadcn/ui (Radix-based) components
+- `i18n/` — `react-i18next` setup with locale JSON in `i18n/locales/`; toggled via `components/LanguageSwitcher.tsx`
 - Path alias: `@` → `./src`
 
 **Core Workflow**: User submits URL → task queued → download video → extract audio (FFmpeg) → transcribe (Whisper/Groq/etc) → generate notes (LLM) → frontend polls for completion → display Markdown + mind map.

 - **Database**: SQLite at `backend/app/db/bili_note.db`, auto-initialized on first run
 - **FFmpeg**: Required system dependency for video/audio processing
 - **Vite proxy**: Dev server proxies `/api` and `/static` to backend (configured in `vite.config.ts`, reads env from parent dir)
+- **Distributed mode (optional)**: Setting `NACOS_SERVER_ADDR` enables Nacos worker registration; setting `RABBITMQ_URL` enables MQ feedback. Both are no-ops when unset — single-node deployment works without either. Other knobs: `WORKER_ID`, `WORKER_SELF_URL`, `WORKER_MAX_CONCURRENT`, `TASK_MAX_WORKERS`.
