- selectBranchIndex compares a discriminator structurally: a `const` may be
an object or array, and deep-link arguments arrive as freshly parsed
instances that could never be reference-equal to the schema's own.
- New applySchemaConstants, applied by InspectorView AFTER the deep link's
`appArgs` are spread over the seeded defaults. The form renders a pinned
field read-only, so a link disagreeing with one would otherwise auto-open an
App with a hidden value contradicting the shape on screen.
