"""Copy the canonical root CHANGELOG.md into the slack-bot package.

The bot's App Home "What's New" tab reads CHANGELOG.md next to app.py in the
Fargate image, so a copy must live under src/slack-bot/. The root file is the
single source of truth; run this after editing it. Pytest fails if the two drift.
