- Implemented new gRPC service `AIService` in `proto/ai/v1/ai.proto` for handling natural language queries. - Generated Go code for the gRPC service and messages in `gen/ai/v1/`. - Created `services/ai-gateway/` directory structure with necessary files for the service. - Added configuration loading and structured logging. - Implemented domain logic for intent parsing and interaction with Home Assistant. - Established outbound adapters for Ollama and Home Assistant with mTLS support. - Updated `go.work` to include the new service and maintain existing dependencies. - Modified `discord-bot` to use the new `ai-gateway` for AI interactions. - Added deployment manifest for Kubernetes and CI/CD configuration for building and deploying the service.
