docs: remove translations & update homepage (#904)

* docs: add GitHub buttons and improve option docs

* chore: replace husky with prepush check

* docs: revamp homepage and switch to custom GitHub buttons

- Make the docs English-only by removing all zh-cn content, the language switcher UI, and related JS/config

- Rework homepage feature cards (Safe & Typed, Pure JavaScript, Shopify & Jekyll, Streaming) and refresh section colors/layout

- Replace buttons.github.io with custom Star/Sponsor buttons featuring a live star count and dark-mode support

- Drop the buttons.js script and tidy banner, header, footer, and share partials

* fix: restore tsconfig settings and changelog build

Re-add suppressImplicitAnyIndexErrors and downlevelIteration removed in
a75033e2c, which broke the rollup TypeScript build on CI. Drop zh-cn
changelog output now that translations were removed.
