run_prompt_turn previously performed a single completion and returned,
leaving tool calls unexecuted. It now mirrors start_directive's loop:
call -> execute tools -> merge results -> continue until no tool results,
then check the pending-agents guardrail before returning.
The pending-agents guardrail injects a reminder prompt when sub-agents
are pending, matching the same loop termination semantics as --headless.
The session is NOT exited between turns (unlike start_directive) so
multi-turn ACP conversations retain history across session/prompt calls.
Manual gate (tool-probe agent, fs_write + fs_read tools):
id 3 result: {"output":"DONE:probe.txt","stopReason":"end_turn"}
