fix: use cross-platform path separators in Rust compiler test

- Use filepath.Join() in test to generate expected path with OS-appropriate separators
- On Windows, paths use backslash instead of forward slash
- Add case-insensitive PATH prefix check to match implementation
- Fixes Windows CI test failure
