Confirmed modes across positions.length mic positions (spec §3d, §9.3). Every position's own
candidate peaks are matched against every OTHER position's within one bin; a peak that survives
the match at every position is a mode. Pure: no state carried between calls — a caller building
up positions one at a time (the stability criterion, §9.3 ruling 3) simply calls this again with
one more entry and compares the result to the previous call, see roomModeSetIsStable.
