chore(docs): add adoption metrics generation and service

 Services use a **dual-loading pattern**: first attempting to load from local `static/*.json` files, then falling back to fetching from public CDN if unavailable.

+- `pnpm run generate:adoption`: refreshes the public adoption metrics snapshot from npm, jsDelivr, and GitHub public APIs. This task is not part of normal CI because it uses live public network data.
