addKiltMods

Kilt runs NeoForge mods on Fabric, but keeps its guests in KiltLoader.mods instead of registering them, so collect's platform enumeration never sees them. Probed by class presence, Kilt being no dependency of ours. NeoForgeMod.getModFile() already points at the remapped (intermediary) jar, so what lands on the compile classpath is in the namespace the runtime uses.
