Refactor project and index handling

- Standardized formatting across key functions in `project.rs`.
- Updated `index::handle` and `build_index` to incorporate the `config` parameter.
- Improved index-building logic to include project details and enhanced issue tracking.
- Replaced variable names like `files` with `paths` for clarity in `scan.rs`.
