The sub-composites (`e_rou_<id>_eng`, `_wep_*`) are LOCAL detail rigs: their
nodes are posed in their own frame, not ship-space, so folding them in placed
the engines at ~mid-ship (Z≈99) instead of aft — the "floating in air" parts.
The PRIMARY composite (`e_rou_<id>`, the one with the most nodes) already carries
the full ship-space layout: every hull body AND every `GN_*` hardpoint frame
(GN_Bridge at the stern, GN_Engine aft, GN_ShieldG amidships…). Assemble from
that one composite only; engines/bridge/shield now resolve to their real aft/mid
frames. Robust to the odd single-composite case (e108's `e_rou_e108_Missile_open`
is still picked as its own primary).
