/* 
  MongoLite: A MongoDB‑like library for in‑memory POJOs,
  supporting both query expressions (filtering) and an aggregation pipeline.
  
  Updated to TypeScript and enhanced with:
    – New operators: $slice and $filter
    – Modern JS features: optional chaining (?.), nullish coalescing (??), Array.prototype.at()
    – Simple pipeline optimization (merging consecutive $match stages)
    – Cursor support via async iterators
    – Some improvements in array operation efficiency (e.g. in $addToSet)
