Type Conversion Functions

The new WebIDL implementation includes more robust type conversion with better error handling:

• Integer conversions now properly handle edge cases for signed/unsigned values
• Improved handling of enforceRange and clamp options
• More descriptive TypeError messages when conversions fail

Example of improved error messages:

• Old: Generic conversion errors
• New: "Argument is not a finite number" or "Argument is not in byte range"
