The old 'cyc2 combine at cycletype=1CYC' probe over-fired on trivial
passthrough cyc2 terms. Replace with one that fires only when a 2-cycle
triangle actually consumes TEXEL1 (the G_CC_INTERFERENCE particle case) and
dumps both texunits' tile/tmem/fmt/siz. One Silo capture then shows whether
TEXEL1 resolves to the fire tile (tmem 392, RGBA16) or something wrong.
Build clean; bunker1 verify PASS.
