Zephyr Events – A 2KB TypeScript event emitter that's race-condition safe

I built a tiny event emitter that fixes a bug most people don't know they have: if a handler calls off() on itself during emit, the next handler gets skipped. EventEmitter3, Node's built-in EventEmitter, and mitt all have this problem. Zephyr Events uses snapshot-based iteration so handlers can subscribe, unsubscribe, or clear listeners mid-emit without side effects. If you don't need that safety, there's a zephyrEventsFast mode that's up to 82% faster. 1.9KB, zero dependencies, tree-shakeable
