GitHub PR Export Script

This script uses the GitHub CLI (gh) to fetch pull requests from a repository, filter them by label, and format the results into a text file.
It’s especially useful for generating release notes from merged PRs.

---

Prerequisites

1. Install the GitHub CLI

   On macOS (Homebrew):

   brew install gh

   Or see full installation instructions.

2. Authenticate with GitHub

   Run:

   gh auth login

   You only need to do this once. The CLI will prompt you to log in via web or token.

3. Verify authentication

   gh auth status

   You should see your GitHub username and authenticated host.
