sprmn24 2d7182f72c fix(delegate): move heartbeat thread start inside try block to prevent orphan
_heartbeat_thread.start() was called before the try/finally block that
contains _heartbeat_stop.set(). If _register_subagent() or any code
between .start() and try: raised an exception, the finally block would
never run — leaving the heartbeat thread as an orphan that continues
calling _touch_activity() on the parent agent, incorrectly resetting
gateway timeout counters.

Move _heartbeat_thread.start() to be the first statement inside the
try block so the finally block always reaches _heartbeat_stop.set()
regardless of how the child run completes or fails.

Root cause: heartbeat start outside try/finally scope
Impact: orphan heartbeat thread incorrectly resets parent gateway timeouts
