Refactor Runtime Type Checks to Utilize Value-Derived Type Validation

[MidnightDesign]

This refactor introduces a significant change to the runtime type checking mechanism across the codebase. Previously, each type had an associated assertion function responsible for validating its values. The new implementation shifts this responsibility to a more dynamic approach where the type is deduced directly from the value, and then it is validated to determine if it is a subtype of the expected type.

Key changes include:

• Elimination of the Assert class: The dedicated assertion functions have been removed, as the logic for type validation is now incorporated within the Type class and related expressions.
• Improved Error Handling: The error messages generated during evaluation now reflect the exact types encountered, providing clearer feedback on type-related issues.
