Introduce the `Topology` trait to ensure that `Maestro` can compile-time safely bind compatible `Scores` and `Topologies`. This refactoring includes updating `HarmonyTuiEvent`, `ScoreListWidget`, and related structures to work with generic `Topology` types, enhancing type safety and modularity.
Add a .gitignore file to exclude target, private_repos, and log directories. Update TftpScore and HttpScore file paths in `main.rs` to use relative paths from the project root. Modify `HarmonyTUI` initialization in `lib.rs` to create log directory if it doesn't exist before setting the log file path.
