Minor Changes

• #5467 d54cc47 Thanks @davidkpiano! - Add wildcard '*' support for store.on('*', …) to listen to all emitted events. The handler receives the union of all emitted event types.

  const store = createStore({
    context: { count: 0 },
    emits: {
      increased: (_: { upBy: number }) => {},
      decreased: (_: { downBy: number }) => {}
    },
    on: {
      inc: (ctx, _, enq) => {
        enq.emit.increased({ upBy: 1 });
        return { ...ctx, count: ctx.count + 1 };
      }
    }
  });
  
  store.on('*', (ev) => {
    // ev:
    // | { type: 'increased'; upBy: number }
    // | { type: 'decreased'; downBy: number }
  });
