fix: sync claude-opus-5 entry between models.json mirrors

[Copilot]

pkg/cli/data/models.json and actions/setup/js/models.json are required mirrors but diverged: actions/setup/js/models.json was missing the claude-opus-5 pricing entry added to the primary file.

Changes

• actions/setup/js/models.json — added missing claude-opus-5 Anthropic model entry to match pkg/cli/data/models.json:

  "claude-opus-5": {
  "cost": {
  "input": "5e-06",
  "output": "2.5e-05",
  "cache_read": "5e-07",
  "cache_write": "6.25e-06"
  },
  "provider_type": "anthropic"
  }

make validate-models-json-sync now passes.
