docs(whoop): correct the sync overlap comment after the workout widening

The header comment still described WHOOP_RECOVERY_SLEEP_OVERLAP_MS as 24 h
and claimed workout ingest used the narrow default. The constant has been
7 days, and workout ingest now shares it so a late phone-sync to the WHOOP
cloud no longer drops the workout outside the window. Comment only.

  * The incremental window starts from `lastSyncedAt - overlap`. WHOOP re-scores
  * recovery/sleep hours after the night, so the overlap must comfortably cover
- * the re-score lag — `WHOOP_RECOVERY_SLEEP_OVERLAP_MS` is 24 h; workout/cycle
- * use the smaller `WHOOP_DEFAULT_OVERLAP_MS`.
+ * the re-score lag — `WHOOP_RECOVERY_SLEEP_OVERLAP_MS` is 7 days, now shared by
+ * workout ingest too (a phone that syncs to the WHOOP cloud well after a
+ * workout would otherwise fall outside a narrow window and never land);
+ * `WHOOP_DEFAULT_OVERLAP_MS` stays the narrow fallback for other resources.
