v1.3.4

Bug Fixes

• Compress old experiment history in proposal prompt to reduce LLM context usage (keeps last 2 full, summarizes older to bullet points ~40-60k tokens vs ~121k)
• Fix factor result.h5 lookup path in _evaluate_factor_directly and _save_factor_values (was using Qlib template workspace, now correctly uses CoSTEER sub-workspace)
• Fix Series.to_frame().to_parquet() in factor value saving
• Correct bars-per-day documentation: 1440 bars/day (1-min data), not 96
• Update prompts to accept 2024-only debug dataset output as valid factor result
