Add Claude Opus 4.7 to Claude Code OAuth models

[rdself]

Summary

• add Claude Opus 4.7 to the Claude Code OAuth catalog and local static model list
• add Opus 4.7 specs, pricing metadata, extended-context handling, and family fallback coverage
• update tests and docs, and verify CC-compatible providers inherit the new model automatically

Why

Claude Code now exposes Opus 4.7 as the current Opus model. OmniRoute should surface it consistently in the OAuth provider, the mirrored CC-compatible catalog, and the related capability metadata.

Validation

• node --import tsx/esm --test tests/unit/provider-models-route.test.ts tests/unit/cc-compatible-model-catalog.test.ts tests/unit/models-catalog-route.test.ts tests/unit/t31-t33-t34-t38-model-specs.test.ts

claude-opus-4-7 family fallback skips claude-opus-4-6-thinking. This can miss the best/available fallback on providers like antigravity where the Opus 4.6 entry is claude-opus-4-6-thinking (and claude-opus-4-6 may not exist). Consider adding claude-opus-4-6-thinking ahead of claude-opus-4-6 in the claude-opus-4-7 fallback list.

cc pricing for claude-opus-4-7 duplicates the same rate block as claude-opus-4-6. To reduce drift risk when rates change, consider factoring this into a shared constant (or aliasing 4-7 to the 4-6 pricing entry) rather than repeating the literal values.
