v2.2.0 Social login google/github

Added

• Social Login Support: Integrated Google and GitHub authentication into the Clean Architecture and MVC templates.
• Expanded Validation Matrix: Scaled the mathematical validation matrix to 7,920+ unique project scenarios, ensuring 100% template rendering accuracy across all permutations.

Changed

• Clean Architecture Restructuring: Moved use cases from src/domain/usecases to src/usecases (Application Layer) to strictly follow architectural boundaries.
• Improved EJS Alignment: Optimized all templates with whitespace-slurping tags (<%_, _%>) to eliminate redundant blank lines in generated code.
• Environment Validation: Added social authentication credentials to Zod-based environment schemas.
