* feat(v2): Support swizzling TypeScript components
* Add tsc --noEmit to tsc script in theme-classic
Now everything can pass the type checker! (although still a lot of any)
* Add tsconfig and types.d.ts to website
Improve developer experience.
As an example, I converted NotFound to tsx
* Apply type annotation suggestions
* Do not fallback to `getThemePath` if getTypeScriptThemePath is undefined
* Fix tsc
* Add module declaration for @theme-original/*
* Move babel cli to root package.json
