End-to-end verified after manually appending claude-opus-4-7 to a Claude MAX OAuth channel's supportedModels:

$ curl -sS -X POST https://<axonhub>/anthropic/v1/messages \
    -H 'x-api-key: <key>' \
    -H 'anthropic-version: 2023-06-01' \
    -H 'content-type: application/json' \
    -d '{"model":"claude-opus-4-7","max_tokens":50,"messages":[{"role":"user","content":"reply with the single word: pong"}]}'

HTTP 200, 1.6s
{
  "id": "msg_01FP2EX5APhWxvSC3eh2Np8Y",
  "type": "message", "role": "assistant",
  "content": [{"type": "text", "text": "pong"}],
  "model": "claude-opus-4-7",
  "stop_reason": "end_turn",
  ...
}

So the route works end-to-end against api.anthropic.com on the OAuth/MAX path; the only thing missing in unstable is the FetchModels short-circuit list, which this PR fixes so new claudecode channels pick up 4-7 without manual supportedModels patching.

Greptile Summary

This PR adds claude-opus-4-7 to the hardcoded DefaultModels() list in the Claude Code transformer, which is the static list returned by FetchModels for OAuth/MAX channels that cannot hit the live Anthropic models endpoint.

• Adds a single entry \"claude-opus-4-7\" to claudecode.DefaultModels(), consistent in shape with the existing claude-opus-4-6 and claude-sonnet-4-6 entries (no date suffix).
• The model ID already exists in frontend/src/features/models/data/providers.json, so the UI metadata is already in place; this change wires the backend model-fetch path to surface it for Claude Code channels.

Confidence Score: 5/5

Safe to merge — one-line addition to a static list with no logic changes.

The change is a single string appended to a hardcoded slice. The model ID matches what's already registered in providers.json, the surrounding list follows the same dateless-suffix convention used for 4-6 models, and there are no control-flow, auth, or data-path changes involved.

No files require special attention.
