// RuntimeSettings represents runtime configuration that can be changed dynamically.
// This struct is used for:
// - API responses (GET /api/settings)
// - API requests (POST /api/settings)
// - Persisting to runtime_settings.json
// - Loading from runtime_settings.json on startup
//
// All fields are pointers to distinguish between "not set" and "set to zero/false value".
