Subject: [PATCH] fix: collapse inactive workshop sidebar groups

Keep the current workshop prominent by collapsing category and workshop groups by default. Starlight expands the branch containing the active lesson. Document this convention for future sidebar additions.

 ## Site config
 
 - `astro.config.mjs` — Site URL, base path, `locales` block, sidebar (manually maintained).
+  Workshop categories and workshop groups default to collapsed; Starlight automatically expands the branch containing the current page. Keep this behavior when adding groups so similarly named workshops in different categories are not confused.
 - `src/content.config.ts` — Content collection loader. Its `base` points at `../docs`, so lesson Markdown is sourced from the repo-root content directory. Excludes underscore-prefixed directories so support assets such as `_images/` aren't routed as pages.
 - `src/components/` — Site-shell components (`.astro`). Lesson content does **not** live here.
 - `src/pages/` — Standalone Astro routes outside the content collection. Currently just `shared/0-prereqs.astro`, the full-HTML redirect that forwards the legacy `/shared/0-prereqs/` URL to the home page (prerequisites are now per-harness at `/<harness>/0-prerequisites/`).
