Refactor code for improved readability and maintainability

- Simplified multi-line function calls in `PatchTree.lua` and `SHA1.luau` for better clarity.
- Enhanced the `init.lua` file by formatting the `PatchTree.build` function call across multiple lines.
- Updated `change_processor.rs` and `api.rs` to improve the formatting of function calls and enhance code consistency.
- Made minor adjustments in test files to streamline assertions and improve readability.

These changes contribute to a cleaner codebase and enhance overall maintainability.
