- Update challenge method to return (bool, String) tuple - Include key
ID in both success and failure cases - Update tests to verify key ID
matches expected value - Maintain same verification logic but provide
additional context

- 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

- Add instance_incremental_transfer module for handling incremental data transfers
- Add test_incremental_transfer module for testing incremental transfer functionality
- Update TCP connection library to support new incremental transfer features
- Update Cargo.toml dependencies for TCP connection utilities
- Update main library to integrate new TCP connection functionality

- Remove handle, target, target_configure, target_connection modules from main library
- Create test_utils module in test project to contain temporary connection functionality
- Update import paths in test files
- Keep instance and error modules as core functionality
- Adjust vcs_test configurations to adapt to new test structure

- Add rmp-serde dependency for MessagePack serialization
- Implement write_msgpack and read_msgpack methods for basic MessagePack support
- Add write_large_msgpack and read_large_msgpack methods for chunked transmission
- Add error conversions for rmp-serde errors
- Add comprehensive tests for MessagePack functionality
- Fix code formatting and improve readability
- Make stream field pub(crate) for better access control

All tests pass successfully, ensuring backward compatibility.

- Convert manual async functions to async fn syntax
- Replace assert_eq!(true/false, ...) with assert!(...) and assert!(!...)
- Fix useless vec warning by using array directly
- All tests continue to pass after optimizations

- Rename from_str to from_address_str in tcp_connection to avoid trait conflict
- Use ? operator instead of let...else patterns in local and vault initialization
- Replace manual string slicing with strip_prefix in virtual_file.rs
