Not approved. This will lead to substantial subagent build up and kill RAM

* revert(coding-agent): restore subagent cleanup guidance Reverts #1952 so agents delete direct subagents when they are no longer needed instead of retaining them until a user explicitly requests deletion. Adds prompt coverage for the intended cleanup policy. * test(coding-agent): keep prompt rollback free of copy assertions

The delegation section of the system prompt instructs the model to "Delete a direct child explicitly with
await rlm.delete_subagent(child)when it is no longer needed." Models follow it: finished subagents get deleted routinely, destroying their sessions and any warm context that would make them cheap to reuse for follow-up work. Idle children cost little to keep.The sentence now reads: "You can delete a direct child explicitly with
await rlm.delete_subagent(child). Only do this if and when a user asks for it." The capability stays documented; the default behavior flips from delete-when-done to keep-unless-asked.Prompt-content tests still pass unchanged (they pin the call form, not the old sentence).

Note
Restrict subagent deletion to user-requested only in
buildRlmPromptUpdates the delegation guidance in the RLM system prompt so that explicit deletion of a direct child subagent occurs only when the user asks for it. Previously the prompt directed deletion when the child was no longer needed. Idle children now remain available for follow-ups.
