Fix neo-ux-core package.json to match lockfile dependencies

Restore missing devDependencies (tsup, typescript, eslint, @types/*) that were in the lockfile but removed from package.json. This was causing CI failures with "pnpm-lock.yaml is not up to date" errors.

- Add back devDependencies: @types/react, @types/react-dom, eslint, tsup, typescript
- Add private: false for npm publishing
- Add sideEffects: false for tree-shaking
- Add lint script
- Reorder exports with types first (best practice)
