Refactor code for improved clarity and maintainability

- Added `#[allow(clippy::too_many_arguments)]` annotations in `change_processor.rs` and `matching.rs` to suppress warnings for functions with multiple parameters.
- Updated `serve_session.rs` to include `clippy::type_complexity` in the `#[allow(dead_code)]` annotation for better code quality.
- Simplified array initialization in `file_names.rs` for consistency.
- Enhanced texture filtering logic in `matching_fixtures.rs` by replacing `map_or` with `is_some_and` for improved readability.

These changes contribute to a cleaner codebase and address static analysis warnings, ensuring better maintainability.
