Enhance Policy Auto-Discovery to Support Subdirectories

[Usmanzahidcode]

Currently, Laravel requires users to manually register policies in 'AuthServiceProvider' unless they follow the exact naming convention and place them directly in 'app/Policies'. However, policies within subdirectories are not automatically discovered, even when they adhere to Laravel’s default naming conventions. This forces unnecessary manual registration and limits flexibility in organizing policies.

Proposed Enhancement:
Laravel should automatically resolve policies located within subdirectories of 'app/Policies' without requiring explicit registration. Manual registration should still be supported for:

• Policies with custom names that don’t align with Laravel’s convention.
• Complex systems where policies require fine-grained control.

This enhancement would improve the developer experience by reducing boilerplate while maintaining flexibility for advanced use cases.
