Add Claude Code GitHub Action Workflow

Overview

This PR introduces automated Claude Code integration via a new workflow claude-code.yml.
Claude will now run on every pull request (and pushes to main/master) to provide AI-powered code review, documentation suggestions, and quality checks.

Key Changes

• Added .github/workflows/claude-code.yml
  • Triggers on PR events (opened, synchronize, reopened) and direct pushes.
  • Uses anthropics/claude-code-action@v1.
  • Requires repository secret ANTHROPIC_API_KEY.
• Default settings left minimal; advanced claude_args section is commented for future tuning.

Setup Required

1. In Repo → Settings → Secrets and variables → Actions, add
   ANTHROPIC_API_KEY = <your-Anthropic-API-key>.
2. Merge this PR.
3. Open / update a PR or push to main to see Claude comments appear.

How to Test

1. Fork/clone this branch locally.
2. Push a dummy commit or open a test PR – GitHub Actions should run the new Claude Code job.
3. Confirm that the workflow completes without error and that Claude posts a review or log in the Actions tab.

Acceptance Criteria

• Workflow file exists and is valid YAML.
• Pipeline triggers on PR events and pushes to main/master.
• Job finishes successfully on CI.
• Claude output visible in PR conversation or Actions log.

Note: Customize the commented claude_args block in the workflow if you want to pin a model version, change tool permissions, or set max turns.
