Typed adapter handle for a PMTiles archive, reachable through
Source.protocol("pmtiles"). Provides the archive-metadata inspection
surface (HonuaPmtilesArchive.describe) that the tiles-only PMTiles
Source uses to participate in the Dataset model honestly. The first
describe() call is cached so repeated inspection does not re-open the
archive.
Inspect the archive and return its normalized metadata. Cached after the
first successful call; a failed inspection is not cached so a transient
fetch error can be retried.
