ship_capture: bake e106 COMPLETE from the 2026-07-26 F10 capture — all 8 parts

The second F10 capture (ship at _m LOD distance) closes e106 entirely: all 8
parts placed including the bridge both earlier captures missed, cross-validating
the doc's 7 known translations to 0.1 units and adding brg_01 at the exact
centreline (0, 153.3, -164.0).

Matching hardened by what the real capture taught us:
- LOD-aware: each part tries every variant vcount (base/_m/_l/_d) — a distant
  ship draws its LOD copies, same local frame.
- Position-validated, SET-based, against the UNION of a part's variants: buffer
  order != decode order, and one draw's vcount equalled the _m count while its
  buffer held the FULL 1633-vert geometry. A coincidental vcount (foreign
  51-vert mesh vs the bridge) is rejected by geometry.
- Runtime mirror handled: twins share one file geometry; the engine uploads the
  starboard copy X-reflected. Mirror-validated draws bake diag(-1,1,1) and the
  viewer reverses triangle winding for det<0 so front faces stay outward.
- Near-axis rotation entries snapped to exact 0/+-1 for a clean table; eng_01
  keeps its genuine 30-degree nacelle rotation.

data/ship_placements.txt now ships e106 (viewer renders via the captured table);
embedded_e106_is_complete locks the baked data. part_pos + capture_match helper
examples added. 10 ship_capture tests; 80 formats-lib tests green; viewer builds.
