Add ProjectZomboidMapLog (map.txt)

Per-line world object placement/removal log. LINE pattern handles both
integer and floating-point coordinates and both 'Base.X' and
'IsoObject (X)' object encodings. Detectors: filename match plus content
signature on the added/removed verbs paired with Base./IsoObject prefix.
