* fix(harness): resolve runtime paths from project root
* docs(config): update
* fix(config): address runtime path review feedback
* test(config): fix skills path e2e root
* test(config): cover legacy config fallback when project root lacks config files
Verifies that when DEER_FLOW_PROJECT_ROOT is unset and cwd has no
config.yaml/extensions_config.json, AppConfig and ExtensionsConfig fall back
to the legacy backend/repo-root candidates — the backward-compat path
requested in PR #2642 review.

* feat(channels): add DingTalk channel integration
Add a new DingTalk messaging channel using the dingtalk-stream SDK
with Stream Push (WebSocket), requiring no public IP. Supports both
plain sampleMarkdown replies and optional AI Card streaming for a
typewriter effect when card_template_id is configured.
- Add DingTalkChannel implementation with token management, message
routing, allowed_users filtering, and markdown adaptation
- Register dingtalk in channel service registry and capability map
- Propagate inbound metadata to outbound messages in ChannelManager
for DingTalk sender context (sender_staff_id, conversation_type)
- Add dingtalk-stream dependency to pyproject.toml
- Add configuration examples in config.example.yaml and .env.example
- Update all README translations with setup instructions
- Add comprehensive test suite (test_dingtalk_channel.py) and
metadata propagation test in test_channels.py
- Update backend CLAUDE.md to document DingTalk channel

* fix(channels): address PR review feedback for DingTalk integration
- Replace runtime mutation of CHANNEL_CAPABILITIES with a
`supports_streaming` property on the Channel base class, overridden
by DingTalkChannel, FeishuChannel, and WeComChannel
- Store stream client reference and attempt graceful disconnect in
stop(); guard _on_chatbot_message with _running check to prevent
post-stop message processing
- Use msg.chat_id as the primary routing key in send/send_file via
a shared _resolve_routing helper, with metadata as fallback
- Fix process() return type annotation from tuple[str, str] to
tuple[int, str] to match AckMessage.STATUS_OK
- Protect _incoming_messages with threading.Lock for cross-thread
safety between the Stream Push thread and the asyncio loop
- Re-add Docker Compose URL guidance removed during DingTalk setup
docs addition in README.md
- Fix incomplete sentence in README_zh.md (missing verb "启用")

* fix(channels): fix isinstance TypeError and add file size guard in DingTalk channel
Use tuple syntax for isinstance() type check to avoid runtime TypeError
with PEP 604 union types. Add upload size limit (20MB) before reading
files into memory. Narrow exception handlers to specific types.

* fix(channels): propagate markdown fallback errors and validate access token response
- Re-raise exceptions in _send_markdown_fallback to prevent partial
deliveries (files sent without accompanying text)
- Validate _get_access_token response: reject non-dict bodies, empty
tokens, and coerce invalid expireIn to a safe default
- Add tests for both fixes
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(channels): validate upload response and broaden send_file exception handling
- Validate _upload_media JSON response: handle JSONDecodeError and
non-dict payloads gracefully by returning None
- Broaden send_file exception tuple to include TypeError and
AttributeError for unexpected JSON shapes

* fix(channels): fix streaming race on channel registration and slim outbound metadata
- Register channel in service before calling start() to avoid race
where background receiver publishes inbound before registration,
causing manager to fall back to static CHANNEL_CAPABILITIES
- Strip known-large metadata keys (raw_message, ref_msg) from outbound
messages to prevent memory bloat from propagated inbound payloads

The lark-oapi SDK defaults to open.feishu.cn (China), but apps on the
international Lark platform (open.larksuite.com) fail to connect with
error 1000040351 'Incorrect domain name'.
Changes:
- Add 'domain' config option to feishu channel (default: open.feishu.cn)
- Pass domain to both API client and WebSocket client
- Update config.example.yaml and all README files
Add LangSmith tracing setup instructions across the project:
- .env.example: add LANGSMITH_* env vars (commented out)
- README.md + translations (zh/ja/fr/ru): add LangSmith Tracing section
under Advanced with setup steps and env var reference
- backend/README.md: add detailed LangSmith Tracing section with setup,
env var table, how-it-works explanation, and Docker notes
- docker-compose.yaml: update LANGCHAIN_TRACING_V2 to LANGSMITH_TRACING
for naming consistency with the rest of the project
