Fix Clippy warnings and optimize code

- Fix let_underscore_future warning by properly awaiting async functions
- Make accept_import function async to match add_mapping usage
- Propagate errors properly with ? operator instead of ignoring them
- Replace manual Default implementation with derive attribute
- Replace vec! with array literal to avoid useless_vec warning
- All tests pass and code is now Clippy clean
