feat(gradio): timeout fallback to bundled mock_ui charts and summary

feat: custom_hf without CUDA falls back to offline baseline

perf(ui): fewer Gradio steps + live STEPS_PER_EPISODE, tighter token cap

perf(space-ui): faster Gradio custom_hf — UI candidates=1, cap tokens, GenerationConfig

Space T4 + real HF path: split requirements, GPU defaults, API reset behavior

Finalize eval-friendly defaults: offline baseline, deterministic API reset, docs cleanup

docs+router: HF Space secret names; auto includes custom_hf only when HF_TOKEN set

fix(router): exclude custom_hf from auto chain so Space auto stays fast

perf(ui): default mock provider; auto tries NIM/OpenRouter before HF; cap HF router timeout 90s

fix(space): ProxyHeadersMiddleware + uvicorn proxy flags so Gradio redirects use https behind HF

fix(space): mount Gradio at / for HF iframe; disable SSR; curl path + blank UI notes; example step JSON

fix(api): Pydantic v2 step payload (exclude_none); env candidate_solutions; README Space API curl guide; Gradio API tab

Add Dockerfile, Docker Compose, and GitHub Action to publish Docker image to GHCR

feat: inference router (HF/NIM/OpenRouter/mock); README aligned with judge rubric; chart axis labels

Add Gradio app for Hugging Face Space and GitHub Actions auto-deploy workflow (sanitized)

Final cleanup for FORGE-v4: Colab entrypoint, OpenEnv API, 10x optimization, and Judge Narrative generation

Run app.py, generate logs/charts, and update guide.md
