fix(website): cache GitHub stars on server for 3 hours (#730)

Browse Source 
Move star count fetching from universal +layout.ts to server-only code
so the GitHub API is not called on every page load or client navigation.

Add an in-memory cache with a 3-hour TTL and in-flight request
deduplication. On API errors (including rate limits), return the last
successful value when available.
