Add ProjectZomboidUserLog (user.txt)

Two row variants: low-level Connection events and player join/disconnect
events. The LINE regex accepts both shapes; analysers route via
CONNECTION (action/index/guid/id) and PLAYER_EVENT (steamid/player/event)
named-group regexes. Detectors: filename match plus content signatures
on either variant.
