Generate palette projections at module build (#50)

*palcus.itp files are Toolset-derived snapshots (category skeleton + blueprint descriptors). This makes Crucible the generator: module builds strip stale descriptors from the committed skeletons and inject descriptors computed from the source-tree blueprints (NAME/STRREF + RESREF, plus CR/FACTION for creatures, faction names resolved via repute.fac). Compare applies the same projection; extract never writes *palcus.itp back into source, so local Toolset palette mess stays local.

Companion PR in sow-module strips the committed palcus files down to skeletons.
