The `plist` XML decoder throws on the legal dictionary key `__proto__`
(its CVE-2022-22912 guard). An app whose XML Info.plist held such an
entry could not be opened at all ("app has no readable
CFBundleExecutable"), and entitlements, XML keyed archives, and
Interface Builder plists failed the same way. On the plutil JSON route,
validation silently dropped the key from `inspect_plist` results.
Decode XML plists through a shared reader that substitutes such keys
before the decoder runs, then omits and counts those entries.
`inspect_plist` and `inspect_keyed_archive` report the omission as a
limitation instead of failing or dropping it silently.

Foundation encodes `encode(_:forKey: "UID")` as a `$top` dictionary
whose single key is `UID`. The keyed archive projection treated every
one-key `UID`/`CF$UID` dictionary as a reference marker, so that root
became a malformed reference and the real link to its object was lost.
Treat a one-key dictionary as a UID only when its value is a number,
matching the binary decoder's UID shape and Foundation's XML `CF$UID`
rule; otherwise descend into it as an ordinary dictionary.
