Fix Claude action authentication to use github_token instead of OAuth app

[Copilot]

The Claude Code workflows were failing with 401 Unauthorized because they required the Claude Code GitHub App to be installed. The app is not installed on this repository.

Changes

• .github/workflows/claude.yml: Replace claude_code_oauth_token with github_token and anthropic_api_key
• .github/workflows/claude-code-review.yml: Same authentication change

# Before
with:
  claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}

# After
with:
  github_token: ${{ secrets.GITHUB_TOKEN }}
  anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}

This aligns with the authentication pattern already used by the custom Claude actions in .github/actions/.

Note: Requires ANTHROPIC_API_KEY secret to be configured in repository settings (appears to already exist based on other workflows).

If you instead wish to use this action with a custom GitHub token or custom GitHub app, provide a github_token in the uses section of the app in your workflow yml file.

@copilot - why is this check skipped Claude Code / claude (pull_request_review)

The check was skipped because the workflow has a conditional that only runs when the comment/review contains '@claude'. Your comment mentions '@copilot', so the workflow's if condition (line 20-24 in claude.yml) evaluated to false and skipped execution. The workflow would only run if you mention '@claude' in a comment or review.
