shikihane c368b5b359 feat(feishu,tools): add outbound media delivery via send_file tool (#1156)
* feat(feishu): implement SendMedia and add send_file tool

Add outbound media support for the Feishu channel so the agent can send
images and files to users via the MediaStore pipeline.

Feishu channel:
- SendMedia dispatches media parts as image or file uploads
- sendImage uploads via Image.Create then sends image message
- sendFile uploads via File.Create then sends file message
- feishuFileType maps extensions to Feishu file_type values

send_file tool:
- New tool lets the LLM send a local file to the current chat
- Validates path, registers file in MediaStore, returns media ref
- Agent loop wires tool registration, MediaStore propagation, and
  context updates

Tested on Radxa Cubie A7A (arm64) with Feishu websocket channel.

* fix(agent): publish outbound media regardless of SendResponse flag

The SendResponse flag controls whether the agent loop publishes the
final text response (callers that publish it themselves set this to
false). However, the media publish path was also gated behind this
flag, which meant tool-produced media was silently dropped for normal
channel messages.

Media should be published immediately when a tool returns media refs,
independent of how the text response is delivered.

* fix(tools): use magic-bytes MIME detection and add file size limit to send_file

- Replace hardcoded extension-to-MIME map with h2non/filetype (magic
  bytes) + mime.TypeByExtension fallback, consistent with the vision
  pipeline in resolveMediaRefs
- Add configurable max file size check (defaults to config.DefaultMaxMediaSize,
  20 MB) to prevent oversized uploads
- Add tests for magic-bytes detection, extension fallback, size limit,
  and default max size

* refactor(agent): add ForEachTool to AgentRegistry for cross-agent tool lookup

Extract the pattern of iterating agents to find a named tool into
AgentRegistry.ForEachTool, simplifying SetMediaStore propagation.

* fix(agent,tools): adapt send_file to ctx-based channel injection after upstream refactor

Replace ContextualTool interface (removed upstream) with direct ctx
reading in SendFileTool.Execute, using ToolChannel/ToolChatID helpers.
Remove updateToolContexts which is no longer needed since ExecuteWithContext
already injects channel/chatID into ctx for all tools.

* feat(tools): support toggling send_file tool via config

Add SendFileConfig with Enabled field to ToolsConfig, defaulting to
true. Wrap send_file tool registration in loop.go with the config
check, consistent with the pattern used by other tools.
