#15844
Adds a **Chat channels** capability so a RAGFlow assistant (Dialog) can
be exposed as a bot on external messaging platforms (Feishu/Lark,
Discord, Telegram, Slack, WeCom, LINE, etc.). An admin configures a bot
in the UI, connects it to an assistant, and inbound messages are
answered from that assistant's knowledge base — replies are delivered
back on the channel.
**Feishu/Lark is implemented and tested end-to-end.** Discord, Telegram,
LINE, and WeCom are scaffolded against the same interface; the remaining
listed channels are tracked as follow-ups.
### Design
**Backend**
- New `chat_channel` table (`tenant_id`, `name`, `channel`, `config`
JSON holding `{credential: {...}}`, `dialog_id`, `status`) +
`ChatChannelService` and RESTful CRUD under `/api/v1/chat_channels`.
- Channel framework under `api/channels/`: a `core` registry +
per-channel packages that self-register a builder and implement a common
`Channel` interface (`start`/`stop`/`send` + inbound normalization) over
`IncomingMessage`/`OutgoingMessage`.
- Embedded **reconcile loop** in `ragflow_server`
(`api/channels/bootstrap.py`): loads enabled bots, and
starts/stops/restarts them as rows change (no server restart needed).
Inbound messages run the connected dialog via the non-streaming
completion path, keeping per-end-user conversation history.
- Missing optional channel SDKs degrade gracefully (channel skipped with
a warning; others unaffected). Channel-level errors are logged, not
crashed.
- Feishu's WebSocket client runs in a dedicated thread with its own
event loop to avoid cross-loop/contextvars conflicts with the channel
runtime.
**Frontend**
- **Settings → Chat channels** panel: available-channels grid +
configured-bots list with add/edit/delete and a **Connect assistant**
popup that binds a bot to a dialog.
- Brand icons via simple-icons / reused shared data-source assets, with
colored fallbacks for brands not available.
- Route, sidebar entry, i18n (en/zh), and a top-nav segment-boundary fix
so the settings page no longer highlights the Chat tab.
### Type of change
- [x] New Feature (non-breaking change which adds functionality)
### Notes
- DB: new `chat_channel` table is auto-created; `chat_channel.dialog_id`
is also covered by a `migrate_db` `alter_db_add_column` for existing
installs.
- Channel SDKs (`lark-oapi`, `discord.py`, `python-telegram-bot`,
`line-bot-sdk`, `wechatpy`, `aiohttp`) added to dependencies.
- Screenshots / per-channel credential docs to follow.

### Use uv run python3 x.py instead of uv run x.py
When directly call `uv run x.py` it will use the python in shebang, it
does not work if the default python lack of some packages, so change it
to best practices `uv run python3 x.py`

## Summary
Add a complete Turkish translation of the README and include a Turkish
language badge across all existing README files.
## Changes
- **New file**: `README_tr.md` - Full Turkish translation of README.md,
covering all sections (What is RAGFlow, Demo, Latest Updates, Key
Features, System Architecture, Get Started, Configurations, Docker
Image, Development from Source, Documentation, Roadmap, Community,
Contributing)
- **Updated 9 existing README files** (README.md, README_zh.md,
README_tzh.md, README_ja.md, README_ko.md, README_id.md,
README_pt_br.md, README_fr.md, README_ar.md) to include the Turkish
language badge in the language selector
## Impact
- 10 files changed, 417 insertions
- Follows the same structure and conventions as other language-specific
README files (README_ja.md, README_ko.md, etc.)
- Turkish badge uses the same styling pattern (highlighted with DBEDFA
in README_tr.md, standard DFE0E5 in others)
