Explain the internal working of CrewAI's memory system when memory=True is set?

1. When a Crew is instantiated with memory=True, CrewAI automatically constructs default instances of ShortTermMemory, LongTermMemory, and EntityMemory rather than requiring each to be built manually
2. The crew's embedder configuration is passed into the ShortTermMemory and EntityMemory constructors, since both rely on embeddings for similarity-based retrieval
3. LongTermMemory is initialized without an embedder, since it isn't built around embedding-based similarity search the way the other two are
4. ChromaDB serves as the default vector storage backend underlying this memory system, persisting the embedded data

This automatic wiring is what lets a single boolean flag produce a fully functioning three-tier memory system, while still leaving the door open to override any individual memory type with a custom instance when the defaults don't fit.
