feat(trellis_mac): close the fal quality gap — RAM-sized bake cap + forced-opaque alpha
Local GLBs were crushed to exactly 94,535 faces (fal ships ~495k) by the
200k laptop mtlbvh guard + o_voxel cleanup, and noisy baked alpha flipped
materials to BLEND (speckle-veil hair, 'broken face'). Neither was the
diffusion — local decode was already 2.2M tris.
- run.py: default TRELLIS2_MAX_BAKE_FACES by node RAM (>=96GB -> 500k,
else 200k laptop-safe); pass max_bake_faces/alpha_mode/steps/baker
params through (server forwards only client-sent params — manifest
defaults are UI-only)
- manifest: new params, quality defaults
- BENCHMARKS.md: 2026-07-22 entry — 500k cap verified crash-free on M3
Ultra, 351,898-face GLB, bake 7s->14s, farm-path e2e verified
