fix: resolve TypeScript type generation and import issues

Fixed two critical bugs preventing frontend build:

1. **TypeScript Type Generation (CommonJS/ESM)**
   - TypeGen generates CommonJS by default but Vite requires ESM
   - Created scripts/generate-types.sh to automate proper generation
   - Script modifies tsconfig.json to output ESM and recompiles TypeScript

2. **useCore.ts Import**
   - Fixed import to use Model instead of ViewModel
   - ViewModel was removed in previous refactoring (commit 3957347)

These fixes resolve the frontend build error where Rollup couldn't import
CommonJS modules from TypeScript files.
