refactor: riorganizzazione script — Strategy ABC, folder strategies/waste/analysis

- src/strategies/base.py: Strategy ABC con Signal, BacktestResult, YearlyStats
- src/strategies/indicators.py: keltner_ratio, detect_squeezes, ema, atr, rv, corr
- scripts/strategies/: SQ01-SQ04 (squeeze puro/filtri), ML01 (squeeze+GBM)
- scripts/waste/: W01-W22 script scartati + REF originali
- scripts/analysis/: compare, best_yearly, final_report, paper_status
- CLAUDE.md aggiornato con nuova struttura e tabella strategie

 ## Convenzioni
 
-- Script numerati progressivamente (`01_`, `02_`, …). Ogni script è autocontenuto.
+- Strategie in `scripts/strategies/` con codice univoco (SQ01, ML01, ...).
+- Script scartati in `scripts/waste/` con prefisso W01-W22.
 - Diario in `docs/diary/YYYY-MM-DD.md`. Aggiornare dopo ogni esperimento significativo.
 - Nessun dato sensibile nei commit (token, chiavi API). Usare `.gitignore`.
 - Verificare sempre assenza di data leakage prima di fidarsi dei risultati. In particolare: `returns[i-w : i]` include `close[i]` che è un candle nel futuro — usare `returns[i-w : i-1]`.

+"""ML01 — Squeeze + GBM (Gradient Boosting Machine) Walk-Forward.
+
+Strategia ibrida: squeeze breakout come pre-filtro (QUANDO tradare),
+GradientBoosting su features strutturali come conferma (QUALE direzione).
+
+Pipeline:
+    1. Rileva squeeze release (Bollinger esce da Keltner)
+    2. Estrai 44 features dalla finestra (structural multi-window + squeeze
+       metadata + price position + ATR + momentum breakout)
+    3. GBM walk-forward: train su 50% rolling, step 10%, predice direzione
+    4. Trade solo se ML ha confidenza ≥ ml_threshold
+
+IN:
+    - OHLCV DataFrame
+    - Parametri: bb_window (14), sq_threshold (0.8), brk_bars (3),
+                 ml_threshold (0.70), leverage (3), position_pct (0.15)
+
+OUT:
+    - BacktestResult con metriche walk-forward (no data leakage)
+    - Solo periodo di test (seconda metà dati)
+
+Risultati tipici:
+    ETH 15m bb14 ml=0.70: 76.9% acc, 1213 trades, DD 4.2%, €13.78/day
+    BTC 15m bb14 ml=0.70: 78.8% acc, 1964 trades, DD 7.0%, €5.51/day
+    BTC 1h  bb14 ml=0.70: 77.3% acc,  617 trades, DD 6.7%, €3.85/day
+
+Note:
+    - GBM = GradientBoostingClassifier di scikit-learn
+    - Walk-forward: nessun look-ahead, train sempre prima di test
+    - Il baseline squeeze puro ha accuracy più alta (~79.5%) ma DD peggiore
+    - Il valore del ML è filtrare breakout deboli → DD ridotto
