Bootstrap (IMPORTANT do this first, every time)

Paths note: All paths in this skill are relative to .agents/skills/pie-design-system/ unless stated otherwise.

Check whether .versions exists.
If missing → ensure the three core packages are installed (@justeattakeaway/pie-webc, @justeattakeaway/pie-css, @justeattakeaway/pie-icons-webc), then run:
```
node .agents/skills/pie-design-system/scripts/fetch-references.mjs
```
Make sure to check if the skill is being setup in a monorepo, as the packages may be resolved to the root node_modules folder. Also check if the Skill is installed local to the application, or globally as this will affect the path when running the setup script.
If present → compare versions in .versions against the installed package versions (node_modules/@justeattakeaway/pie-webc/package.json etc.). Re-run the script if any version differs. Otherwise proceed to the next section.
