Subject: [PATCH] test(whoop): cover WHOOP workout cross-source resolution in
 the read-time picker

Prove a WHOOP run and the same Apple-Health run inside the 5-minute clustering
window collapse to the APPLE_HEALTH canonical row (richer GPS + HR record),
and a lone WHOOP run survives when no richer source logged the session. The
measurement-side WHOOP/Apple/Withings oracle already lives in
source-priority-whoop-applehealth.test.ts; this closes the workout axis.
