Adds an integration test for the new behavior introduced in https://github.com/openai/codex/pull/9011. The work to create the test setup was substantial enough that I thought it merited a separate PR. This integration test spawns `codex` in TUI mode, which requires spawning a PTY to run successfully, so I had to introduce quite a bit of scaffolding in `run_codex_cli()`. I was surprised to discover that we have not done this in our codebase before, so perhaps this should get moved to a common location so it can be reused. The test itself verifies that a malformed `rules` in `$CODEX_HOME` prints a human-readable error message and exits nonzero. |
