CTY Conversion

The pyvider.cty.conversion module provides type conversion and unification capabilities for transforming values between different cty types.

Key functions: - convert(value, target_type) - Convert a CtyValue to a different type when possible (e.g., number to string, string to number) - unify(types) - Find the most specific type that can represent all given types (type unification)

Conversion vs Validation: Conversion is more flexible than validation - it attempts to transform values between compatible types, while validation strictly checks conformance to a type schema. For example, convert(CtyString().validate("123"), CtyNumber()) succeeds and returns the number 123, while CtyNumber().validate("123") fails because the input is not already a number.

Type conversion is essential for building flexible APIs that accept multiple input formats and for implementing polymorphic functions that work across different types.
