Lowers VRAM_FRACTION_MIN from 0.80 to 0.0 so the memory planner can assign as little as 0% of a GPU's VRAM to the active model, enabling forceful layer spreading across multiple GPUs.

  • backend: vram_budget_settings.py floor 0.80 -> 0.0
  • frontend: per-model-config.ts slider min 80 -> 0
  • tests: updated valid/invalid ranges in both suites
