Module agent_builder 

Agent builder — constructs a runnable agent from a ManagedAgentDef.

The build_agent function is the bridge between the declarative agent definition and the live LlmAgent that the session loop drives. It wires:

• Model (Arc<dyn Llm>) + system prompt → LlmAgentBuilder
• Built-in tool declarations → in-process tool implementations
• Custom tools → ManagedCustomTool wrappers (park via ToolParkingLot)
• Permission policy → ToolConfirmationPolicy
• Description → agent description

MCP servers and skills are noted but their full integration is deferred to later tasks (MCP toolset lifecycle, skill injection).
