build: migrate site from GitBook to VitePress

The legacy gitbook CLI (gitbook@3.2.3) crashes under Node 24 because the
bundled send module reads res._headers, which no longer exists. Rather
than patch dead tooling, switch the build to VitePress:

- add .vitepress/config.mts with sidebar converted from SUMMARY.md,
  local search, edit links, footer and zh-Hans UI
- repoint package.json scripts to vitepress (serve/build/preview), drop
  gitbook and its plugins; regenerate package-lock.json
- update the Pages workflow to upload .vitepress/dist
- refresh README usage notes and Makefile help/clean targets
- prefix relative <img> src in windows-build with ./ so Vite resolves them
- remove obsolete book.json and scripts/gitbook.js
