feat(ILO-391): static World capability enforcement (world-no-net + ILO-T044)
Add two builtins for composing World capability tokens: - `world-and w1:W w2:W > W` — intersection (each cap is w1.cap AND w2.cap) - `world-or w1:W w2:W > W` — union (each cap is w1.cap OR w2.cap) The verifier propagates static knowledge through both ops: world-and statically denies a cap if either input statically denies it; world-or statically denies only when both inputs statically deny it, enabling ILO-T044 to fire correctly for composed worlds. 23 regression tests + examples/world-compose.ilo added.
