PR Summary

This pull request introduces the "nopejs Bot," a new GitHub Action designed to automatically summarize pull requests using the Google Gemini API.

Key changes include:

• New Bot Functionality: Adds a GitHub Action that triggers on PR events (opened, synchronize, reopened) to generate and post a summary.
• Permissions: Configures the workflow with pull-requests: write and contents: read permissions, essential for commenting on PRs and reading their content.
• Workflow Enhancements: Passes PR_NUMBER and GITHUB_REPOSITORY as environment variables to the Python script and captures the script's output to a file.
• New README: Introduces a README.md file detailing the bot's purpose and functionality.
• Script Updates: The main.py script is updated to use the new PR_NUMBER environment variable, include a debug check for the Gemini API key, and print the summary to standard output.
• Setup Improvements: setup.py is modified to dynamically read the README.md for the long description and streamline package discovery, aligning with a potential change in project structure (e.g., Python source moving to the root).
