Add ProjectZomboidPerkLog (PerkLog.txt)

Per-line skill snapshot log; each Login event is paired with a perks
row containing comma-separated Skill=N tokens. PERK_PAIR regex extracts
each pair via preg_match_all for analyser use. Detectors: filename
match plus content signature on the unique '[Cooking=N, Fitness=N,
Strength=N,' prefix of the perks-row bracket.
