A declared hash that the local dump contradicts is not one situation. An
existence platform never reads the bytes, so withholding the file lets an
upstream list error remove something the frontend would have loaded; a
hash platform would reject it, so shipping it is pointless.
The mode now decides, at every point that had an opinion: pack building,
core complement, emulator packs, manifests, conformance and
_intentional_hash_exclusion. verify.find_undeclared_files follows, since
verify and generate_pack must agree file for file.
Also here: resolution reports which evidence matched rather than a flat
"exact", a path or filename can no longer override a declared hash, and
safe_extract_zip treats a Windows backslash as the separator it is
instead of refusing the archive.
