chore(mypy): add mypy and type stub packages to dev deps

Add mypy and type stub packages to dev dependencies to support type checking:
- mypy: Static type checker
- types-jsonschema, pandas-stubs, types-psutil, types-tqdm: Type stubs for third-party packages
- boto3-stubs: Type stubs for AWS SDK

This is Phase 1 of the mypy suppression removal plan, which will enable us to eliminate ~30 type checking errors related to missing type information for third-party packages.
