MechaCat02 015e49ac8a ship: diagnostics — baked-table renderer + evidence the placement IS static ...

ship_render example: assemble a ship from the baked capture table (or --static)
and write orthographic top/side PPM renders + per-part world bounds — the
offline eye for placement bugs.

Findings recorded (docs to follow with the fix):
- e106 baked eng_01 is CROSS-INSTANCE contamination: the F10 capture de-dups by
  vertex-buffer address alone, so for a part drawn by several fleet ships only
  the FIRST instance's transform survives; eng_01's 30-degree rotation and
  below-hull position belong to a different destroyer. Fleet formation made it
  reproduce across captures, defeating the cross-validation.
- The static composite DOES carry the exact placement: BE-f64 +-264.0 (the
  lateral hull pair offset the static assembler loses) and -164.044 (the bridge
  Z we captured as -164.037) sit in e_rou_e106's node joint tables. The static
  decode is incomplete, not the data — full static assembly is achievable, with
  captures demoted to a verification oracle.
