* fix(formats): preserve high bits in remaining magic-byte checks
Node's "ascii" decoder masks the high bit, so byte-for-byte signature
comparisons accepted lookalikes such as CD DA ("MZ" | 0x80) or a
high-bit "bplist00"/"NIBArchive" header. ac57c88ef fixed this for the
shared DOS/MZ reader; apply the same latin1 decoding to the remaining
signature checks: NativeAOT and Windows native loader MZ/PE, binary
plist and NIBArchive detection, and PNG IHDR checks.
Display-name decodes (section and metadata stream names) are unchanged.
