Add Claude Code GitHub Workflow

Problem Statement

We want to integrate Claude Code into our CI/CD pipeline to assist with [automated code reviews / bug detection / generating documentation] on Pull Requests. Currently, this process is manual.

Proposed Solution

Create a new GitHub Action workflow (.github/workflows/claude-code.yml) that triggers on specific events.

Acceptance Criteria

Create a new workflow file.

Configure the workflow to trigger on pull_request [or push to main].

Set up the necessary environment variables (ANTHROPIC_API_KEY) in repository secrets.

Ensure the workflow installs the Claude Code CLI tool.

Run Claude Code against the diff/codebase.

Verify that the output is [logged to the console / posted as a PR comment].
