Store this state manager to ByteRover:

class StateManager {
  constructor(initialState = {}) {
    this.state = initialState;
    this.listeners = new Set();
  }
  
  subscribe(listener) {
    this.listeners.add(listener);
    return () => this.listeners.delete(listener);
  }
  
  setState(updates) {
    this.state = { ...this.state, ...updates };
    this.listeners.forEach(listener => listener(this.state));
  }
}
