Add ProjectZomboidClientActionLog (ClientActionLog.txt)

Strict 5-field bracketed format. Parser captures only the timestamp;
analysers that want steamid/action/player/coords/param decompose the
Line text via ClientActionPattern::FIELDS. Detectors: filename match
plus content signature on the IS{Enter,Exit}Vehicle / ISWalkToTimedAction
action tokens.
