- Add routing.dto.ts with validation DTOs for create, update, and reorder operations - Add routing.controller.ts with full CRUD: GET list, POST create, PATCH update, DELETE remove, PATCH reorder, GET effective (merged priority view) - Users can only create/modify/delete their own user-scoped rules; system rules are protected with ForbiddenException - GET /api/routing/rules/effective returns merged rule set with user rules taking precedence over system rules at the same priority level (M4-010) - Extend agent-config.dto.ts with capability shorthand fields: domains, preferredModel, preferredProvider, toolSets (M4-011) - Update agent-configs.controller.ts to merge capability fields into config.capabilities so agent's preferred model/provider can influence routing decisions - Register RoutingController in agent.module.ts Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
