refactor(python): migrate pip to uv and inline packages

Replace pip install --user with uv tool install for CLI tools
(ansible) and uv pip install --system for libraries (libtmux, pynvim).
Drop pipx and pipenv (uv replaces both), delete the external
config/asdf/python-packages file, and rename the script to
install-python-packages to reflect the broader scope.
