Alex Kwiatkowski 1dad0a7f4a Make shell detection tests

robust to Nix shell paths (#12476)

## Summary
- Updated `codex-rs/core/src/shell.rs` tests for shell detection to stop
asserting hardcoded shell paths.
- `detects_bash` and `detects_sh` now assert executable basenames
(`bash`, `sh`) rather than `/bin/*`/`/usr/bin/*` absolute paths.
- This keeps behavior the same while avoiding failures in Nix
environments where shells are resolved from `/nix/store/.../bin`.

## Testing
- `nix develop .#default --command sh -lc 'export
PKG_CONFIG_PATH=/nix/store/6az1q591wwlgazzskngr6rl7gmhpyvnc-libcap-2.77-dev/lib/pkgconfig:/nix/store/fgm3pz8486ksh3f94629lpb7xjr2wjp7-openssl-3.6.0-dev/lib/pkgconfig:$PKG_CONFIG_PATH;
export PKG_CONFIG_PATH_FOR_TARGET=$PKG_CONFIG_PATH; cd
/home/alex/workspace/openai/codex/codex-rs && cargo test -p codex-core
--lib detects_bash && cargo test -p codex-core --lib detects_sh'`

## Why
The two failing tests previously hardcoded fixed paths and failed under
the Nix shell due to Nix-provided shell binary locations.

## Links
- Bug report / enhancement request: not publicly filed yet; this was
reproduced in the local Nix environment.

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.

When using the workspace-write sandbox policy, the Seatbelt profile allows writes under the configured writable roots while keeping .git (directory or pointer file), the resolved gitdir: target, and .codex read-only.

Network access and filesystem read/write roots are controlled by SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.

Seatbelt also supports macOS permission-profile extensions layered on top of SandboxPolicy:

no extension profile provided: keeps legacy default preferences read access (user-preference-read).
extension profile provided with no macos_preferences grant: does not add preferences access clauses.
macos_preferences = "readonly": enables cfprefs read clauses and user-preference-read.
macos_preferences = "readwrite": includes readonly clauses plus user-preference-write and cfprefs shm write clauses.
macos_automation = true: enables broad Apple Events send permissions.
macos_automation = ["com.apple.Notes", ...]: enables Apple Events send only to listed bundle IDs.
macos_accessibility = true: enables com.apple.axserver mach lookup.
macos_calendar = true: enables com.apple.CalendarAgent mach lookup.

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.
