Summary

What it is: Fast shim-based version switching with task runner hooks and env var support.

When to use: Many repos with different runtime pins; want one entrypoint instead of nvm plus pyenv plus tfenv.

When to skip: Team already standardized on Dev Container only.

Key features: mise install, global and local config, CI-friendly, compatible with asdf plugin ecosystem patterns.
