  - Add schema, types, methods, and model following codebase conventions
  - Implement auto-seeding of default categories during AppService startup
  - Update marketplace controller to use new data-schemas methods
  - Remove old model file and standalone seed script

refactor: unify agent marketplace to single endpoint with cursor pagination

  - Replace multiple marketplace routes with unified /marketplace endpoint
  - Add query string controls: category, search, limit, cursor, promoted, requiredPermission
  - Implement cursor-based pagination replacing page-based system
  - Integrate ACL permissions for proper access control
  - Fix ObjectId constructor error in Agent model
  - Update React components to use unified useGetMarketplaceAgentsQuery hook
  - Enhance type safety and remove deprecated useDynamicAgentQuery
  - Update tests for new marketplace architecture
  -Known issues:
  see more button after category switching + Unit tests

feat: add icon property to ProcessedAgentCategory interface

- Add useMarketplaceAgentsInfiniteQuery and useGetAgentCategoriesQuery to client/src/data-provider/Agents/
  - Replace manual pagination in AgentGrid with infinite query pattern
  - Update imports to use local data provider instead of librechat-data-provider
  - Add proper permission handling with PERMISSION_BITS.VIEW/EDIT constants
  - Improve agent access control by adding requiredPermission validation in backend
  - Remove manual cursor/state management in favor of infinite query built-ins
  - Maintain existing search and category filtering functionality

refactor: consolidate agent marketplace endpoints into main agents API and improve data management consistency

  - Remove dedicated marketplace controller and routes, merging functionality into main agents v1 API
  - Add countPromotedAgents function to Agent model for promoted agents count
  - Enhance getListAgents handler with marketplace filtering (category, search, promoted status)
  - Move getAgentCategories from marketplace to v1 controller with same functionality
  - Update agent mutations to invalidate marketplace queries and handle multiple permission levels
  - Improve cache management by updating all agent query variants (VIEW/EDIT permissions)
  - Consolidate agent data access patterns for better maintainability and consistency
  - Remove duplicate marketplace route definitions and middleware

selected view only agents injected in the drop down

fix: remove minlength validation for support contact name in agent schema
