feat(claude-cli): add Claude Opus 4.7 to the provider model list

The pinned @mariozechner/pi-ai catalog tops out at Opus 4.6 / Sonnet 4.6
/ Haiku 4.5. Append a Claude Opus 4.7 entry (1M ctx, 128k max out,
$5/$25 per MTok) with id-dedupe so it becomes a no-op once the upstream
catalog catches up. Sonnet 4.6 and Haiku 4.5 remain current per
https://platform.claude.com/docs/en/about-claude/models/overview and
are already in the catalog, so no other additions are needed.
