Overview

Package interp runs python/node/custom (and `set shell`-override) task bodies by writing the interpolated body to a temp file and exec-ing the configured interpreter against it (the just shebang/[script] model). No language runtimes are embedded (Principle V). A missing interpreter is an actionable error.
