This fixes the row order of the tracked strangeness tables written by the AOD producer. - The tracked V0, cascade and 3-body rows were written in strangeness-tracker order, which is not always collision order. - Analyses slicing them by collision then abort with "TraCascIndices index fIndexCollisions is not sorted". - The rows are now written in the per-collision order already built in prepareStrangenessTracking. - The track index of a row no longer comes from a running counter, so a skipped strange track cannot shift the rows after it. https://its.cern.ch/jira/browse/O2-7197 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

This makes the order of the tracked strangeness tables within a collision the same in MC as in data. - SVertexer sorted the strange tracks by decay only when running with more than one thread; MC reconstruction runs it with one. - The strange tracks are now sorted by decay in all cases. - The AOD producer groups them by collision with a stable sort, so the decay order within a collision is kept. https://its.cern.ch/jira/browse/O2-7197 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
