chore: track vendor/scrivo/ in git, update build script to copy bundled dependencies

Update .gitignore to include vendor/scrivo/ (highlight.php) while excluding other vendor packages. Replace composer install in build-zip.sh with explicit rsync of bundled runtime dependencies, excluding dev-only files. Map 'text' language to 'none' in server-side block rendering for consistency with client-side mode.
