Upgrade project to pydantic v2

Migrate pydantic v1 validators to v2 across entire project

Scope of Changes

Files Modified: 30+ files across the entire codebase Lines Changed: Comprehensive updates to type annotations, validators, method calls, and config patterns Tests Verified: 171+ tests passing Linting: All fixable issues resolved

Key Technical Changes

1. Type System Improvements

• 50+ Optional field annotations added
• 8 ClassVar annotations for class variables
• Explicit type annotations for all fields
• Proper Union and Optional usage

2. Validator Modernization

• All decorators migrated to v2 syntax
• None parameter handling added
• Cross-field validation using model_validator
• Dict iteration patterns fixed
• Duplicate validators consolidated

3. API Method Updates

• All .dict() → .model_dump()
• All .parse_obj() → .model_validate()
• All .parse_file() → manual load + .model_validate()
• Config equality using .model_dump()

4. Configuration Patterns

• class Config → model_config = ConfigDict()
• root → RootModel with .root
• Extra.forbid → extra='forbid'

5. Safety Improvements

• None checks before attribute access
• Default config initialization
• Safe dynamic attribute setting

6. Test Adaptations

• Proper pydantic instances instead of MagicMock
• Value-based equality comparisons
• Updated error message assertions
