 * Create the server plugin

 * This creates a RuntimePlugin that:
 * 1. Intercepts all actions and checks for state slice changes
 * 2. Emits state.changed events to the internal bus when slices change
 * 3. Emits execution.lifecycle events for RUNTIME_EXECUTION_* actions
 *
 * Usage:
 * ```typescript
 * const serverPlugin = createServerPlugin({ slices: ["execution", "agent"] });
 * const runtime = createRuntime({ plugins: [agent, serverPlugin.plugin] });
 * const server = createServer({ runtime, plugin: serverPlugin });
 * ```
