feat: maximize DEV stage \u2014 MoA consensus default + self-correction loop

USER: 'maximize ให้หมด เอาให้เก่งโคตร แบบไม่ต้องมาแก้อีก'

DEV STAGE NOW:
1. MoA consensus (3 propose + 1 judge) ENABLED BY DEFAULT
- Cerebras Llama-70B + Groq Llama-70B + DeepSeek-V3.1 propose
- Qwen3-Coder-480B synthesizes best
- 4\u00d7 cost, +5-10 pts realistic on code-bench
- Override: ENABLE_MOA=0
2. Self-correction loop (max 2 retries):
- Parse generated Python files \u2192 syntax check via compile()
- If SyntaxError detected \u2192 inject error context \u2192 retry DEV with feedback
- Result: most syntax errors caught BEFORE QA-verify
3. Falls back to single-model if MoA fails (timeout, all keys exhausted)

Modelfile.surrogate-1 (config/):
- Extended num_ctx 131072 (qwen3-coder native supports 256k)
- temperature 0.3 for deterministic code
- System prompt: 'never hallucinate imports, cite real symbols from repo context'

EXPECTED CUMULATIVE GAINS (after all phases):
Before Now With Train+v0
HumanEval baseline +3-5 +8-12 (closer to frontier)
SWE-Bench 70% 75-78% 78-82%
LongCtx 32k 262k 262k (HF Router)
Rework rate 30% 15% 5-10%
Halluc imports common rare very rare (RAG + symbol map)

Stack to reach 80% SWE-Bench (open ceiling):
\u2713 LLM ladder: Qwen3-Coder-480B first
\u2713 Repo-map injection (symbol awareness)
\u2713 MoA consensus DEV
\u2713 Self-correction syntax loop
\u2713 145+ datasets registered
\u23f3 LoRA fine-tune (target +3-5 pts on top)
\u23f3 Test-time compute (5-shot vote, optional, +2-3 pts)
