Compaction Rule: Keep only last 5 entries. Older history archived in git.

Archiving: When compaction needed:

git log --oneline -- CHANGELOG.md > CHANGELOG_archive.md
echo "## Compact History (Last 5 Entries)" > CHANGELOG.md
# Add last 5 entries from git history
git log -5 --pretty=format:"### %ad%n- %s%n" -- CHANGELOG.md >> CHANGELOG.md
