Fixes #768

docs/.vitepress/cache/ holds Vite's pre-bundled dependencies. It got committed with the doc site in #54, and nothing ignored it, so every local docs:dev run rewrote those 20 files and they showed up in git status.

This removes the directory from the index and adds /docs/.vitepress/cache/ to .gitignore, next to the existing .temp/ and dist/ entries.

Checked locally:

• npm run docs:build passes with the cache directory gone. The Documentation workflow only runs npm install and docs:build, so it doesn't need these files.
• After vitepress dev regenerates the cache, git status shows nothing under docs/.vitepress/cache (those files are now ignored). On main, the same run leaves 8 of the tracked cache files modified.
