Module runner 

Ergonomic child-session runner facade over the canonical spawn core.

ChildRunner is a thin wrapper around the existing SpawnContext (it does NOT introduce a parallel RuntimeDeps god-struct). It builds a SpawnJob and delegates to crate::sdk::spawn::run_child_spawn — the single canonical spawn path.

Sub-agents are plain full agents: there is no per-role tool trimming, so the job’s disabled_tools is always None here (the unrelated global config.disabled_tools path is applied elsewhere, not via this runner).

The assignment prompt and system prompt already live in the persisted child session (matching real spawn semantics: ExecuteRequest.initial_message is empty; the last user message in the child drives execution). RunChildInput therefore stays minimal.
