Fix clippy warnings and optimize code

- 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
- All tests continue to pass after optimizations
