feat(github-copilot): add Claude Opus 4.8 to default model catalog

saju01 · steipete · commit 60580c48679a · 2026-05-31T16:46:17.000+01:00
GitHub Copilot now serves claude-opus-4.8 (verified via live /models
endpoint), but the static default catalog stopped at 4.7, so the model
was invisible in the picker and 'openclaw models list' until added
manually. Add it to both the manifest and the defaults list, mirroring
the existing 4.7 metadata shape.
