James Dansereau d920f32da1 linux-build: cast chrflags->Model in vtxstore modelGetNodeRwData call 
GCC 14 hard-errors enum(CHRFLAG)->pointer as 'incompatible type for
argument' with no controlling warning flag (not downgraded by
-fpermissive / -Wno-error=int-conversion). Line 157 of the same WIP-decomp
function already casts the identical (Model*)var_v0->chrflags expression;
match it on line 162. Codegen-identical.
