fix(iace): close domain-gate gaps — generic patterns with press/welding/glass text

Observed on a real Kistenhubgeraet (lift) project: generic mechanical patterns
(e.g. HP1000 "Quetschen Arm zwischen Pressenteilen") carry NO machine type and
only generic tags (crush_point, rotating_part), so they fired for a lift; the
narrow domain-gate terms missed their press/welding/glass wording.

Broadens domainGateTerms (pressenteil, pressraum, blechbearbeitung,
punktschweiss, schweisselektrod, elektrodenspalt) and adds a dom_glass domain
(glasschneid/glasbearbeitung/...) with its emit keywords. New test pins that the
four observed leakers now require a dom_* tag. Ghost=0, Leakage=0, coverage held
on both GTs.
