fix: use detach() instead of close() on utf8_stdout wrapper to preserve shared buffer

When stdout uses non-UTF-8 encoding (e.g. cp1252 on Windows piped mode),
the interceptor creates a TextIOWrapper around sys.stdout.buffer. Using
close() on teardown destroys the shared buffer, causing ValueError in
subsequent stdout writes. detach() disconnects the wrapper without
closing the underlying buffer.
