Hyu 28bffdef21 fix(mcp): set _preserve_managed_process before finally in cold-start path (#2309) ...

_ColdStartRetry was caught in _lifecycle_loop_with_retry which set
_preserve_managed_process = True — but by then the finally block inside
_lifecycle_loop had already run and called _cleanup_box_stdio_session(),
stopping the live managed process (return_code=143 SIGTERM). The cold-start
retry then restarted a fresh process, eliminating the warm-up advantage.

Fix: add an explicit except _ColdStartRetry in _lifecycle_loop that sets
_preserve_managed_process = True before re-raising. The finally block then
sees the flag and skips stop_managed_process, leaving the live process
untouched for the next handshake attempt.
