Problem

The unit coverage comment on every PR says "No unit baseline recorded in coverage/history.csv yet" and only shows absolute numbers. The coverage history moved from main to the coverage-history branch, but test.yml still runs compare against coverage/history.csv in the checkout, which no longer exists.

Fix

• Before compare, fetch history.csv from coverage-history and pass it with --csv. If the fetch fails, compare falls back to absolute numbers as today, and the step is already continue-on-error.
• The comment footer said history is recorded in coverage/history.csv; it now points at the coverage-history branch.

Testing

Ran the same fetch and compare locally against current unit reports. The comment now reads "Compared against 109b74a on main (#1020)" with a change column per module instead of the no-baseline message. This PR's own coverage comment should show the same.
