Skylar GraikaandSkylar Graika 9008a0eff9 core: prevent shell_snapshot from inheriting stdin (#9735) ...

Fixes #9559.

When `shell_snapshot` runs, it may execute user startup files (e.g.
`.bashrc`). If those files read from stdin (or if stdin is an
interactive TTY under job control), the snapshot subprocess can block or
receive `SIGTTIN` (as reported over SSH).

This change explicitly sets `stdin` to `Stdio::null()` for the snapshot
subprocess, so it can't read from the terminal.

Regression test added that would hang/timeout without this change.
Tests: `ulimit -n 4096 && cargo test -p codex-core`.
