refactor: use tsc for types and explicit .js imports

Reworked the build pipeline to run Vite for JS output and `tsc --project tsconfig.build.json` for declaration generation, replacing `vite-plugin-dts` with native TypeScript emit settings. Internal source imports/exports were updated to explicit `.js` specifiers across configs, providers, renders, and entrypoints to align ESM output and TS 7 behavior. Dev dependencies were also simplified (removing dts/api-extractor-related tooling and unused lint plugin) while upgrading TypeScript to ^7.0.0.
