fix(exec): skip git repo check when --yolo flag is used (#9590)

## Summary

Fixes #7522

The `--yolo` (`--dangerously-bypass-approvals-and-sandbox`) flag is
documented to skip all confirmation prompts and execute commands without
sandboxing, intended solely for running in environments that are
externally sandboxed. However, it was not bypassing the trusted
directory (git repo) check, requiring users to also specify
`--skip-git-repo-check`.

This change makes `--yolo` also skip the git repo check, matching the
documented behavior and user expectations.

## Changes

- Modified `codex-rs/exec/src/lib.rs` to check for
`dangerously_bypass_approvals_and_sandbox` flag in addition to
`skip_git_repo_check` when determining whether to skip the git repo
check

## Testing

- Verified the code compiles with `cargo check -p codex-exec`
- Ran existing tests with `cargo test -p codex-exec` (34 passed, 8
integration tests failed due to unrelated API connectivity issues)
