research(report): resoconto PROTETTO (soft-guard DD -4%) anno-per-anno -> combo + TP01 + GTAA singoli

Report che mette combo (TP01+GTAA 50/50), TP01 e GTAA sulla stessa griglia giorni-di-borsa (esposizione 1x, come dentro al combo), applica la guardia-DD -4% a ciascuna serie e tira fuori per anno: NL (net liquidation da $2000), DD intra-anno, rendimento, Sharpe + riga TOT con CAGR. Combo protetto: CAGR +9.1% / DD 5.8% / Sh 1.38 (2022 -1.8%); baseline +11.3% / 8.4% / 1.48. Aggiunto data/paper_combo/ al .gitignore (stato paper runtime, come gli altri paper dir).

+Mette combo (TP01+GTAA 50/50), TP01 e GTAA sulla STESSA griglia giorni-di-borsa (come dentro al
+combo), applica la guardia-DD -4% a ciascuna serie (de-risk 1.0->0.4 a -4% dal picco, ri-rischia a
+-1.6%), e per ogni anno riporta: NL (net liquidation da $2000), DD intra-anno, rendimento (=CAGR
