v0.5.7: Helper-agnostic diff engine and custom helper support

[0.5.7] - 2026-07-04

Added

• Added support for custom AUR helpers via the AUDIT_HELPER environment variable.

Changed

• Updated the git diff parser regex to be helper-agnostic, allowing the tool to parse incoming package names from various cache directory structures (such as yay, paru, or Shelly).
• Removed hardcoded path logic to ensure fallback compatibility across different distribution setups.
