Generate PR Description

Analyze the git diff between the parent branch and the current branch and create a pull request title and description.

Parent branch: Use "$1" if provided, otherwise default to "main"

Instructions

1. Use git diff <parent-branch>...HEAD and git log <parent-branch>..HEAD to analyze changes
2. Generate a concise, descriptive PR title
