Subject: [PATCH] Enable TypeScript strict compilation flags

Enable erasableSyntaxOnly and isolatedDeclarations for:
- Faster builds with parallel declaration generation
- Better compatibility with fast transpilers (esbuild, SWC)
- More explicit public API types

Add explicit Zod type annotations to validation schemas
to satisfy isolatedDeclarations requirements.
