refactor(rust): cleanup path handling

- Avoids unnecessary string allocation when tracing paths
- Replaces `mut path & path.push()` with `path.join()`
- Avoids unncessary cloning of paths where applicable
- Use `dunce` crate to remove `UNC` prefix
- Improve performance of resolving `~` by avoiding unnecessary string allocations
- Resolve `~`, `$Env:USERPROFILE` and `$HOME` consistenly between different code paths
- Use `PathBuf` instead of `String` for paths in CLI args

I may have missed a couple of places but I think I covered 90% of path handling in the codebase
