Expected Behavior
os_pipe_create_process should be return the pipe of subprocess.
Current Behavior
os_pipe_create_process fails and return NULL.
Steps to Reproduce
- call os_pipe_create_process with flag = "r"
- check the return value of posix_spawn
- it returns 9 (BAD FD)...
- If change flag to "w", everything works fine.
Anything else we should know?

Research direction
Start at the os_pipe_create_process entry point and reproduce the call on macOS 15 with flag "r". Compare its posix_spawn result with the working "w" case; done means the "r" call returns the subprocess pipe instead of NULL while preserving the existing behavior for "w".
