context: Turbo optimization study structure

insight: Turbo studies use 3_results/ not 2_results/. Dashboard already supports both. Use study.db for Optuna-format (dashboard compatible), study_custom.db for internal custom tracking. Backfill script (scripts/backfill_optuna.py) can convert existing trials.


context: Custom database schema not showing in dashboard

insight: DASHBOARD COMPATIBILITY: If a study uses custom database schema instead of Optuna's (missing trial_values, trial_params, trial_user_attributes tables), the dashboard won't show trials. Use convert_custom_to_optuna() from dashboard_db.py to convert. This function drops all tables and recreates with Optuna-compatible schema, migrating all trial data.
