- _output(): use sys.modules.get() instead of unconditional import to
avoid triggering mcp_server's stdout redirect as a side effect
- _output(): write-all loop for os.write() to handle partial writes and
EINTR; fall back to sys.stdout.buffer on OSError
- _output() docstring: remove inaccurate _save_diary_direct reference
- stop_hook_active guard: narrow except to ImportError/AttributeError,
default silent_guard=False (safe: preserves block-mode loop prevention
when config load fails) and log a warning instead of silently changing
behavior
- tests: two new regression tests covering the real-stdout-fd path and
the fd-1 fallback path
