When an agent calls the MCP create_agent tool to spawn a child agent,
the parent-child relationship is now automatically established:
- Added setManagedAgentId() to AgentSession interface (optional method)
- ClaudeAgentSession stores its managed agent ID and includes it as
X-Caller-Agent-Id header when connecting to the agent-control MCP
- AgentManager.registerSession() calls setManagedAgentId() after
registration so the session knows its ID before first prompt
- MCP server extracts X-Caller-Agent-Id header from init request and
stores it as callerAgentId
- create_agent handler auto-injects callerAgentId as parentAgentId
if not explicitly provided
This enables parent agents to spawn child agents that are correctly
associated, so they appear in the parent's Sub-Agents menu instead
of on the homepage.
