When content exceeds 500 chars, it's automatically split into multiple
memories on paragraph boundaries. Each chunk gets the same category,
tags (with part-N-of-M suffix), keywords, and importance. Removes the
old 800 char hard limit from the Pydantic model.

With 375 memories and 1M context window, low limits just hide results.
Agents can still pass a smaller limit when they want fewer results.
