build(ts): TypeScript foundation — tsconfig + typecheck in CI (T1) 

Adopting TypeScript incrementally (the move off plain JS). Upgraded jsconfig ->
tsconfig with strict + noUncheckedIndexedAccess, but allowJs + checkJs:false so
every existing .js/.jsx keeps resolving and running untouched — only .ts/.tsx
get type-checked. Added 'npm run typecheck' (tsc --noEmit) and wired it into
'npm run ci'. Installed typescript 6 + @types/react/react-dom 19. Client-scoped
(Vite resolves the '@/' paths); the CommonJS server is a separate TS story.
