Denis Andrejew 9ce6bbc43e Avoid setpgid for inherited stdio on macOS (#8691)
## Summary
- avoid setting a new process group when stdio is inherited (keeps child
in foreground PG)
- keep process-group isolation when stdio is redirected so killpg
cleanup still works
- prevents macOS job-control SIGTTIN stops that look like hangs after
output

## Testing
- `cargo build -p codex-cli`
- `GIT_CONFIG_GLOBAL=/dev/null GIT_CONFIG_NOSYSTEM=1
CARGO_BIN_EXE_codex=/Users/denis/Code/codex/codex-rs/target/debug/codex
/opt/homebrew/bin/timeout 30m cargo test -p codex-core -p codex-exec`

## Context
This fixes macOS sandbox hangs for commands like `elixir -v` / `erl
-noshell`, where the child was moved into a new process group while
still attached to the controlling TTY. See issue #8690.

## Authorship & collaboration
- This change and analysis were authored by **Codex** (AI coding agent).
- Human collaborator: @seeekr provided repro environment, context, and
review guidance.
- CLI used: `codex-cli 0.77.0`.
- Model: `gpt-5.2-codex (xhigh)`.

codex-core

This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.

Dependencies

Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:

macOS

Expects /usr/bin/sandbox-exec to be present.

Linux

Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.

All Platforms

Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
