- Removed the canonical model variant indexing, selection, and tracking logic from the model registry and resolver. - Eliminated the `canonical` sub-command, tab view, search tokens, and equivalence configuration structures from the CLI and model selector components. - Refined model identification, lookup, and provider fallback resolution to bind exclusively to standard, raw model IDs. - Relocated the equivalence utility script within the catalog package to support script-only policy generation.
