reckless: add uv python env installation method

uv is a python installation and package manager written in
rust.  We can use it to quickly install python package
dependencies and configure our plugin's python virtual environment.
To maintain consistency with our other reckless python
installations, the venv is still activated in a wrapper which then
imports the original python source.

Changelog-added: reckless can now install python plugins using the uv package manager.
