fix: resolve TypeScript compilation errors and configure environment

TypeScript Fixes:
- Update tsconfig.json lib to include ES2017, ES2019, ES2020, ES2022
- Add Node.js types to tsconfig for process, require, module globals
- Exclude test files and scripts from main type checking
- Fix Organization type handling in modelCache.ts

Environment Configuration:
- Create .env.local with all required placeholder values
- Add security notes and rotation instructions
- Configure Supabase, RunPod, HuggingFace placeholders

Dependencies:
- Run npm install to install 1198 packages
- All dependencies installed successfully

Result:
✅ TypeScript compilation now passes with zero errors
✅ Development server runs successfully on http://localhost:3000
✅ All core source files type-check correctly
