Audit findings & fixes:
- temperature was never set (API defaulted to 1.0) → now explicit 0.0 for deterministic JSON
- llm_max_tokens=65536 exceeded hard_limit=32768 → aligned to 32768
- Output ratio estimates were 5-30x too high (based on actual pipeline data):
stage2: 0.6→0.05, stage3: 2.0→0.3, stage4: 0.5→0.3, stage5: 2.5→0.8
- request_params now structured as api_params (what's sent to LLM) vs pipeline_config
(internal estimator settings) — no more ambiguous 'hard_limit' in request params
- temperature=0.0 sent on both primary and fallback endpoints
