reduce to 1+1 steps mesh-only export to fit 120s ZeroGPU budget

fix: 2+2 steps + texture 64 + simplify 0.5 — must fit in 120s GPU budget

fix: remove gr.Progress (ZeroGPU conflict), fix output handling, rembg CPU provider

perf: reduce steps to fit within 120s GPU budget (no more timeout waste)

fix: restore trellis/ source (accidentally removed in previous commit)

fix: robust error handling, pipeline load guard, startup logging

feat: add gr.Progress(track_tqdm=True) for live step progress

perf: reduce to 4+4 steps, texture 256, simplify 0 — fits in 120s GPU budget

fix: load TRELLIS pipeline to CPU at startup for ZeroGPU budget optimization

Change duration=300 to duration=120 (account limit)

Update sdk_version to 5.12.0 to fix ZeroGPU 300s duration limit
