- Update feishu, dingtalk, discord, email, qq, slack, telegram, whatsapp
- Add filter in send() to skip thinking/tool_call/tool_result messages
- Only process is_normal_message (RESPONSE type)

- Add vikingbot/utils/tracing.py with backend-agnostic @trace decorator
- Use ContextVar for session_id propagation through nested calls
- Implement lazy binding to Langfuse via propagate_attributes
- Update AgentLoop._process_message() to use @trace decorator
- Simplify langfuse initialization logging in commands.py
- Add session_id parameter to litellm_provider.chat()
- Clean up redundant code in utils/helpers.py

The trace decorator abstracts observability concerns, allowing future
switching between Langfuse, OpenTelemetry, or other backends without
modifying business logic.

The propagate_attributes function is a module-level export in Langfuse
Python SDK v3, not a method of the Langfuse client instance.

- Import propagate_attributes from langfuse module
- Remove misleading warning when propagate_kwargs is empty
- Reduce log noise by changing info logs to debug

Standardize terminology and clean up tracing/Langfuse integration:

- Rename sandbox_key to workspace_id across agent, memory, and tools
- Delete deprecated langfuse_decorator.py (superseded by tracing.py)
- Fix Langfuse v3 SDK propagate_attributes usage (module-level function)
- Improve session_id extraction with better signature inspection
- Reduce log noise in Langfuse attribute propagation

Add extract_user_id parameter to @trace decorator to enable user
tracking in Langfuse. This allows grouping traces by user in the UI.

- Add extract_user_id parameter to @trace decorator
- Extract user_id from InboundMessage.sender_id
- Pass user_id to Langfuse propagate_attributes
- Update loop.py to use new lambda style for session_id extraction

Remove the entire legacy test suite including:
- Unit tests (test_agent, test_bus, test_channels, test_config)
- Integration tests (test_agent_e2e)
- Test fixtures, utilities, and OpenSpec config
- Test runner tools (tester/)

These tests were outdated and no longer maintained. Future testing
should use a modern testing framework.

- Update default config path to ~/.openviking/ov.conf
- Add interactive chat mode examples (--no-markdown, --logs flags)
- Remove VKE deployment guide section
- Update Docker volume mount paths

Add detailed Google-style docstrings to:
- AgentLoop.__init__() - parameters and examples
- AgentLoop._publish_thinking_event() - event publishing
- ToolContext - all attributes documented
- Tool base class - complete usage example

Improves code maintainability and IDE support.

Server changes:
- Add --with-bot flag to enable Bot API proxy
- Register bot_router at /bot/v1 prefix
- Add bot_api_url configuration option

CLI changes:
- Update ov chat endpoint to /bot/v1/chat
- Fix UTF-8 input handling
- Add endpoint configuration via env var

- Enhance tool registry with better error handling
- Update OpenAPI channel configuration
- Improve session manager with better state handling
- Enhance Langfuse tracing integration with diagnostic logging

- Enhance CLI commands with new agent tool integration
- Move plugin analysis doc to docs directory
- Add RFC for OpenViking CLI ov-chat command
- Add server restart script
