Refactor permission and question services to use Effect

[anandgupta42]

Summary

This PR refactors the permission and question request handling to use the Effect library for better composability and testability. The main changes include:

• New service modules: Created packages/opencode/src/permission/service.ts and packages/opencode/src/question/service.ts that implement permission and question request handling using Effect's ServiceMap pattern
• Simplified public APIs: Updated packages/opencode/src/permission/next.ts and packages/opencode/src/question/index.ts to use the new service layer via the runtime effect
• OpenAPI schema updates: Added PermissionRequest type definition to the SDK's OpenAPI schema with proper validation patterns
• Generated types: Updated SDK type definitions to include PermissionRequest, EventPermissionAsked, and EventPermissionReplied types
• Test improvements: Enhanced permission and question tests to work with the new service-based architecture

The refactoring maintains backward compatibility while improving the internal architecture for better separation of concerns and testability.

Test Plan

• Existing permission and question tests updated to work with new service layer
• Permission request listing and reply functionality verified through updated test suite
• SDK type generation validated with new schema definitions

Checklist

• Tests added/updated
• Documentation updated (if needed)
• CHANGELOG updated (if user-facing)
