chore: sync strict TypeScript compiler flags from deepnote/deepnote (#39)

- Add forceConsistentCasingInFileNames to ensure import paths match exact file casing
- Add skipLibCheck to skip type checking of declaration files for faster builds

These flags align with the strict configuration used in deepnote/deepnote
and improve type safety and consistency across the codebase.
