fix(apple): preserve decoded keyed archive scalar identity

Move plist projection into the graph owner and identify generated scalar
wrappers by producer identity through every dictionary/UID consumer. Remove
the intermediate JSON clone that erased those facts. Literal wrapper-shaped
dictionaries remain dictionaries; scalar $top values fail as malformed.
Keep numeric projection after graph interpretation, preserve unknown counts,
and retain binary prototype-key partial facts with an explicit limitation.

Adapt @Jax367's relevant scalar proposal and public regression from PR #4317.
Add scalar-root, literal-root and binary prototype controls. Correct only
the captured Foundation data node expectation and its manifest digest;
original producer bytes and source are unchanged. Unrelated PR changes excluded.

Validation: 175 focused checks across 23 files pass, one skipped; build,
check:fast and docs:check pass. Public CLI and stdio MCP cover both encodings.
Baseline scalar controls fail; 24 tiny completed CLI cost comparisons retain
ordinary full replies and Evidence IDs byte for byte. No statistical speed
claim, heavy profiling, target execution or real deep-provider verification.
