LoadedDescriptor

A descriptor loaded (and cached) by a BundleSource.

Holds the parsed header/index together with the filepath it was loaded from, so reading entry data always targets the exact bundle version that produced this descriptor — even if the source's active version is swapped concurrently.

The instance owns a reference-counted handle to the cached descriptor. When the JavaScript object is garbage-collected, the handle is released automatically; the underlying descriptor stays alive only while the source cache (see BundleSource.loadDescriptor) or another LoadedDescriptor references it. No manual disposal is required and no memory is leaked.
