Compares consecutive perks-snapshot rows per Steam ID and emits a
SkillProgressionAnomalyProblem for any single skill whose level gained
more than THRESHOLD_DELTA between two snapshots. Login/Logout/LevelUp
event rows are skipped via a perk-pair regex check on the bracketed
event field.
Threshold of 3 reflects PZ's slow leveling pace: typical session bridges
should not produce four-or-more level jumps in a single skill. The
constant is documented inline so operators can tune for modded XP
servers without touching analysis logic.
Synthetic fixture extended with a PlayerSuspect Steam ID carrying two
snapshots: Strength jumps 2 -> 10 (delta +8, triggers), Fitness jumps
2 -> 8 (+6, triggers), Maintenance jumps 0 -> 3 (+3, exactly at
threshold, does NOT trigger). The existing single-snapshot players
remain noise-free.
