- Updated the host function signatures in `nd_host_artwork.go`, `nd_host_scheduler.go`, `nd_host_subsonicapi.go`, and `nd_host_websocket.go` to accept a single parameter for JSON requests. - Introduced structured request and response types for various cache operations in `nd_host_cache.go`. - Modified cache functions to marshal requests to JSON and unmarshal responses, improving error handling and code clarity. - Removed redundant memory allocation for string parameters in favor of JSON marshaling. - Enhanced error handling in WebSocket and cache operations to return structured error responses.
