/**
 * Recursive opendal list feeding the generic listing differ.
 *
 * Reads through the operator directly (one recursive LIST), never through
 * mirage's caches, as the DeltaHook contract requires. Fingerprints use
 * mirage's default: the native ETag when the listing carries one, `mtime|size`
 * otherwise.
 *
 * Some opendal services answer LIST without per-entry metadata (the hf lister
 * does; WebDAV's PROPFIND does not), which would leave every file
 * unfingerprinted and reduce detection to create/delete. When a listed file
 * carries no metadata at all, one `stat` per affected file fills the gap,
 * mirroring what the hf readdir already does for sizes. A backend whose lister
 * is complete never pays for it.
