Research direction

Start by reading issue #2993 and the referenced cachetools _cached.py implementation, then locate PyIceberg’s manifest-cache entry points and any existing cache_info()-like API. Done means the manifest cache exposes useful hit and miss information through a function call, with behavior aligned to the agreed design.
