re: the format layer is NOT exonerated -- assemble_ship draws a non-renderable volume

Did the visual the backlog kept naming as the next step, and it overturns the
conclusion. Rendering e106 from the static assembly and from the baked runtime
capture: the capture has 8 placements, the static assembly 11 -- the same 8 plus
e303_wep_01 x2 and a second e106_eng_01. In the render the destroyer sits inside
a white slab that dwarfs it.

That slab is e303_wep_01: 172 verts, 110 tris, bounds X[-1000,600] Y[-1050,1050]
Z[-2400,2400] = 1600 x 2100 x 4800. A real e106 turret (wep_02_01) is 269x179x417
with 772 tris; the bridge is 105x76x305. So it is not a turret -- it reads as a
collision/trigger volume, and whatever it is the game does not draw it: the e106
capture contains no e303_wep_01 at all.

Why it was missed: assemble_ship treats every rou_* composite node as drawable,
the cross-id mount is documented as intended, and the test asserts
count("e303_wep_01") == 2. The capture's silence was explained as vbase dedup,
but dedup would show one instance, not zero -- and the test walks capture parts
looking them up in the static output, so EXTRA static placements cannot fail it.
Same shape as the earlier include_external gap: a test that can only fail one way.

Scope stated carefully: sweeping 335 ships for "ship-scale span with <400 tris"
flags 20 ships and 58 placements over 28 resources, but ONLY the e106 case is
proven (render + capture absence + geometry). Others may be legitimately large
low-poly parts and need the same three checks.
