fix(us-bf-026): rename ModelMetaData to ModelMetadata for consistent casing

[ooples]

Summary

• Renamed ModelMetaData<T> class to ModelMetadata<T> (lowercase 'd') in src/Models/ModelMetadata.cs
• Updated IFullModel interface to reference ModelMetadata<T> instead of ModelMetaData<T>
• Renamed GetModelMetaData() method to GetModelMetadata() in IModel interface
• Updated all 95+ references across the codebase (neural networks, regression, time series, etc.)

Problem

The codebase had inconsistent casing: the class was named ModelMetaData<T> (capital D) but many files referenced ModelMetadata<T> (lowercase d), causing compilation errors:

• CS0246: The type or namespace name 'ModelMetadata<>' could not be found
• CS0535: Class does not implement interface member 'GetModelMetaData()'

Solution

Standardized all references to use ModelMetadata (lowercase 'd') which is the more conventional C# naming for "metadata" as a compound word.

Files Changed

• Core files (3):

  • src/Models/ModelMetadata.cs - Class renamed
  • src/Interfaces/IFullModel.cs - Interface reference updated
  • src/Interfaces/IModel.cs - Method renamed

• References updated (95+ files across):

  • Neural networks (30+ files)
  • Regression models (20+ files)
  • Time series models (20+ files)
  • Genetics algorithms
  • Cross validators
  • AutoML models
  • Transfer learning

Build Status

✅ Casing-related errors (CS0246, CS0535) resolved
⚠️ Other pre-existing build errors remain (unrelated to this fix)

Test Plan

• Build verification shows CS0246/CS0535 errors are resolved
• All references to ModelMetaData successfully updated to ModelMetadata
• Method calls updated from GetModelMetaData() to GetModelMetadata()
