Grouping resolution mode for <mj-burst-cluster-strip>.
'auto': Adaptively chooses session bursts for compact histories or calendar eras (year / quarter / month)
when multi-year data exceeds EraZoomThreshold.
'session': Groups chronologically adjacent events into active bursts (within SessionGapHours or same calendar day),
iteratively merging closest adjacent bursts down to MaxClusters.
'day' | 'week' | 'month' | 'quarter' | 'year': Groups events into explicit calendar buckets.
