v0.40.3

ControlMesh v0.40.3

This release adds the first Feishu group controlled-agent handoff slice.

Highlights

• Adds per-Feishu-group agent routing policy with agent_roster, default_agent,
  allow_interagent_handoff, and max_handoff_depth.
• Supports explicit named-agent routing from Feishu groups with syntaxes such as
  @coder ..., agent:coder ..., agent=coder ..., and @agent:coder ....
• Routes selected group requests through the existing ControlMesh multi-agent bus
  and returns labeled results to the original Feishu group/reply target.
• Keeps v1 bounded to one controlled handoff: the Feishu entry agent consumes the
  allowed hop and sends remaining_handoff_depth=0 to the selected agent.
• Keeps unknown or out-of-roster agent targets on the normal main-agent path.
• Stops treating Feishu @all as an explicit bot mention trigger.
• Documents the v1 product boundary in docs/feishu-controlled-agent-handoff.md.
