Update configuration loading with Cargo.toml path and clean up .gitignore

---

This commit message concisely communicates the key changes:

1. The code now builds an absolute path to the `Cargo.toml` file, enhancing clarity in configuration loading.
2. The addition of `PathBuf` usage improves type safety.
3. The removal of unnecessary entries from `.gitignore` helps maintain a clean project structure.

These updates reflect improvements in both functionality and project organization.
