PR Summary: AI PR Summary Workflow

WHAT Changed

• Introduced a new GitHub Actions workflow (ai-pr-summary.yml) to automatically generate a summary of pull requests using OpenAI's API.
• The workflow triggers on pull request events (opened, synchronized, reopened).
• It fetches the PR diff, sets up a Python environment, and generates a summary based on the diff.

WHY It Matters

• Automates the code review process by providing concise summaries of PRs, improving developer efficiency.
• Helps maintainers quickly understand changes, potential risks, and testing needs without manually reviewing each line of code.

RISKS

• Dependency on OpenAI API may lead to failures if the API is down or if the API key is misconfigured.
• The AI-generated summaries may not always accurately reflect the changes, leading to potential misunderstandings.

TESTS to Add

• Unit tests for the Python script that generates the summary to ensure it handles various diff formats correctly.
• Integration tests to verify that the workflow executes successfully under different PR scenarios.

BREAKING CHANGES

• None identified; this is a new feature addition.

Key Features

• AI-Powered Summarization: Uses OpenAI's GPT model to generate summaries of PRs.
• Heuristic Fallback: If AI summarization fails, a heuristic method generates a fallback summary based on diff analysis.
• PR Commenting: Automatically comments the generated summary on the PR for easy visibility.
