Module spawn_worker 

spawn_worker tool: first-class coordinator-pattern delegation.

Unlike the lower-level sub_agent tool (which the LLM can use for arbitrary sub-tasks), spawn_worker is designed for the coordinator pattern where a lead agent explicitly delegates structured work to specialist workers.

Motivation: The old TeamOrchestrator approach required the LLM to write DELEGATE:<role>:<task> text strings, which were then parsed — a fragile, non-type-safe mechanism. spawn_worker gives the coordinator agent a proper JSON tool call to express delegation, eliminating text parsing entirely.
