* fix(native): retain valid Objective-C properties beside a malformed record

readObjcPropertyList decoded a whole property_list_t in one operation.
When a later entry's name pointer was unmapped, the list-level catch
discarded the properties already decoded. An empty property name passed
decoding and then failed schema validation of the whole result, so
inspect-native-dispatch-metadata exited 1 with no metadata.

Each property_t entry is now decoded on its own. A failing entry, or an
empty name, becomes a property_decode_failed issue at the entry address,
and sibling properties are retained. Incomplete-attribute issues also
report their entry address. List-header failures still fail only that
list.

Fixes #3336

* test(native): cover property record isolation on every platform

Move the synthetic Objective-C property Mach-O into a shared fixture and
decode it through decodeAppleDispatchMetadata in a portable test, so
Linux and Windows runs also catch a regression that drops valid sibling
properties. The macOS CLI cases keep exercising the built command.
