🤖 Augment PR Summary

Summary: This PR removes instance-location reporting from the inspect CLI output.

Changes:

• Drops printing of Instance Location lines and removes the instances section from inspect's JSON output.
• Switches inspect framing to SchemaFrame::Mode::References (no longer computing instance data).
• Updates the vendored sourcemeta/core dependency and removes instance-location tracking from SchemaFrame and the schema walker iterator entries.
• Removes JSON Pointer template support from the vendored JSON Pointer API (and related hashing/stringify helpers).
• Updates alter-schema rules to preserve branch order while deduplicating allOf/anyOf, and adds reference re-mapping hooks for transformations.
• Adjusts inspect CLI golden tests to match the new output format.

Technical Notes: The core framing code now focuses on locations/references only, reducing compute/memory previously used to derive unresolved instance locations.

SchemaFrame::references_to() compares against Location.pointer (root pointer), but this check builds entry_pointer from location.relative_pointer. If the schema has nested $id/base changes, relative_pointer can differ from the root pointer and this may miss existing references to an allOf branch, allowing an unsafe elevation.
