mise Project Isolation Pattern

This is a reference pattern. Learn from the approach, adapt to your context — don't copy verbatim.

Problem: Multiple projects on the same machine share runtimes. A global Node or Python version satisfies no project precisely and contaminates others.

Solution: mise activates per-project tool versions automatically on cd. One .mise.toml per project replaces the need for nvm, pyenv, fnm, rbenv, and asdf individually.
