fix(cli): suppress OSError EINVAL on macOS kqueue stdin registration

[CN-big-cabbage]

Problem

On macOS with uv-managed Python (cpython-3.11.11-macos-aarch64), Hermes crashes with a full traceback on exit:

Traceback (most recent call last):
  ...
  File "prompt_toolkit/input/vt100.py", line 165, in _attached_input
    loop.add_reader(fd, callback_wrapper)
  ...
OSError: [Errno 22] Invalid argument

Root cause: kqueue cannot register stdin (fd 0) for EVENT_READ and raises OSError with errno.EINVAL (22). The existing handler at cli.py:11937 only suppressed errno.EIO (5), so EINVAL fell through to else: raise.

Fix

Add errno.EINVAL to the suppressed errno set — same silent-pass treatment as EIO — since the root cause is the same uv/kqueue incompatibility already documented in the surrounding comment.

# Before
if isinstance(_stdin_err, OSError) and getattr(_stdin_err, "errno", None) == errno.EIO:

# After
if isinstance(_stdin_err, OSError) and getattr(_stdin_err, "errno", None) in (errno.EIO, errno.EINVAL):

Test plan

• Run hermes on macOS with uv-managed Python (cpython-3.11.11-macos-aarch64)
• Verify no traceback printed on normal exit
• Verify existing behavior unchanged on Linux / Homebrew Python

Closing — superseded by #26077 (merged as commit d3d5916), which preventively probes kqueue at startup and falls back to SelectSelector when fd 0 cannot be registered. The widened except-clause matching EINVAL / EBADF / 'Invalid argument' — which most PRs in this cluster including yours added — is also included.

Thanks for the fix; closing as duplicate of the merged work.
