Pipx unaware of uninstalled Python

[FelisNivalis]

Describe the bug I had python and "pipx:httpie" installed with mise. After uninstalling Python, the executable httpie still links to the removed python interpreter.

To Reproduce

[tools]
python = "latest"
"pipx:*any tool*" = "latest"

Run mise i. Then remove python="latest" and run mise prune.

Expected behavior When uninstalling a python version or doing a mise upgrade, detect and reinstall affected tools; Report such breaks in mise doctor

that's just how pipx works

This could be an interesting feature request rather than a bug.

It would be nice to be able to use any language package manager backends (npm/pipx/cargo) without worrying if you have the correct tooling installed to download and run them.

I'm not sure if this would be considered dependency management as mentioned in the anti-goals
