chore(deps): upgrade algoliasearch from v4 to v5 lite client

- Update CDN paths to dist/lite/builds/browser.umd.js in jsdelivr.yml and unpkg.yml
- Replace local assets/lib/algoliasearch/algoliasearch-lite.umd.min.js with browser.umd.js
- Update librarybot.yml sync source to dist/lite/builds/browser.umd.js
- Update Hugo template fallback path to lib/algoliasearch/browser.umd.js
- Rewrite search.ts algolia integration to use window['algoliasearch/lite'].liteClient (v5 API, removes initIndex compat)
- Update window type declaration in ui.ts to match v5 UMD global
