BREAKING CHANGE

- **Renaming**: Renamed `uvx` to `uvenv` due to a naming collision with a new `uv` command. The
new name better reflects its purpose, combining `uv` with `venv`. You can run `uvenv self migrate` to move your
environments and installed commands from `uvx` to `uvenv`.

Features

- Added `uvenv self migrate` command to facilitate migration from `uvx` to `uvenv` easily.
- Improved error logging (with more context) using `anyhow`.

Updates

- Updated `uv` from 0.2.4 to 0.2.13 and applied necessary patches to work with new/updated APIs.

Documentation

- Updated documentation to reflect the changes and new features introduced in this version.
- Started groundwork on automated testing
