Changelog Generation

Generate a changelog entry for a new release by analyzing merged PRs since the last tag.

Parameters

The user provides:

• Version number -- e.g., 0.5.3
• Additional PRs -- optionally, PRs not yet merged that should be included

Step 1: Gather Data

1. Find the previous release tag: git tag --sort=-version:refname | head -1
2. List all merge commits since that tag: git log <tag>..HEAD --merges --format='%s' | grep -v "Merge branch"
3. Get PR details with: gh pr list --state merged --base main --search "merged:><tag-date>" --json number,title,author --limit 50
4. List contributors: git log <tag>..HEAD --format='%an' --no-merges | sort | uniq -c | sort -rn

Step 2: Identify External Contributors
