Runs every training path the brain has in sequence: Historical Bootstrap (250d × 47 syms) → Auto-Trainer (latest Stooq bars, daily) → Continuous-Learner resolve (settles any pending journal entries) → Calibrator + IsotonicCalibrator + RegimeCalibrator fits.

Expect ~30 seconds total. Network use: ~50 KB of CSV. Safe to re-run anytime.
📚 What each step does
1. Historical Bootstrap — pulls 250 daily bars × 47 symbols from Stooq, reconstructs 22-feature vectors per (sym, day), labels by next-day direction, feeds the global model + every calibrator. Expected output: ~11,000 training rows.

2. Auto-Trainer — pulls only the freshest Stooq bars and trains on rows we haven't seen yet (deduped by date). Picks up everything that happened since the bootstrap ran. Trains main model + per-horizon ensemble (short/mid/long).

3. Continuous-Learner resolve — walks the captured-but-unresolved journal, resolves any entries whose horizon has elapsed, trains on the freshly-labeled pairs.

4. Calibrators — refits Platt (Calibrator), Isotonic PAV (IsotonicCalibrator), and per-regime calibration (RegimeCalibrator) on the populated (predicted, actual) pools so the next prediction is honest immediately.
