feat: 15 nuovi indicatori quant (common + deribit + bybit + macro + sentiment)

Common (mcp_common):
- indicators.py: vol_cone, hurst_exponent, half_life_mean_reversion,
  garch11_forecast, autocorrelation, rolling_sharpe, var_cvar
- options.py (nuovo): oi_weighted_skew, smile_asymmetry, atm_vs_wings_vol,
  dealer_gamma_profile, vanna_charm_aggregate
- microstructure.py (nuovo): orderbook_imbalance (ratio + microprice + slope)
- stats.py (nuovo): cointegration_test Engle-Granger + ADF helper

Deribit (+6 tool MCP):
- get_dealer_gamma_profile (net dealer gamma + flip level)
- get_vanna_charm (vanna/charm aggregati pesati OI)
- get_oi_weighted_skew, get_smile_asymmetry, get_atm_vs_wings_vol
- get_orderbook_imbalance

Bybit (+2 tool MCP):
- get_orderbook_imbalance, get_basis_term_structure (futures dated curve)

Macro (+2 tool MCP):
- get_yield_curve_slope (2y10y/5y30y + butterfly + regime)
- get_breakeven_inflation (FRED T5YIE/T10YIE/T5YIFR)

Sentiment (+3 tool MCP):
- get_funding_arb_spread (opportunità arb compatte annualizzate)
- get_liquidation_heatmap (heuristic da OI delta + funding extreme,
  no feed paid Coinglass)
- get_cointegration_pairs (Engle-Granger su coppie crypto Binance hourly)

Tutto in TDD pure-Python (no numpy/scipy in mcp_common). README
aggiornato con elenco completo. 442 test totali verdi.

+## Indicatori quantitativi disponibili
+
+### Common (`mcp_common.indicators` + `options` + `microstructure` + `stats`)
+- Tecnici: `sma`, `rsi`, `macd`, `atr`, `adx`
+- Volatilità: `vol_cone` (RV multi-window con percentili), `garch11_forecast`
+- Statistici: `hurst_exponent`, `half_life_mean_reversion`, `autocorrelation`,
+  `cointegration_test` (Engle-Granger)
+- Risk: `rolling_sharpe` (Sharpe + Sortino), `var_cvar` (historical VaR/ES)
+- Microstructure: `orderbook_imbalance` (ratio + microprice + slope)
+- Options: `oi_weighted_skew`, `smile_asymmetry`, `atm_vs_wings_vol`,
+  `dealer_gamma_profile`, `vanna_charm_aggregate`
+
+### Deribit (esposti come tool MCP)
+DVOL, GEX, P/C ratio, skew_25d, term_structure, iv_rank, realized_vol,
+indicatori tecnici, find_by_delta, calculate_spread_payoff.
+**Nuovi**: `get_dealer_gamma_profile`, `get_vanna_charm`,
+`get_oi_weighted_skew`, `get_smile_asymmetry`, `get_atm_vs_wings_vol`,
+`get_orderbook_imbalance`.
+
+### Bybit
+Ticker, orderbook, OHLCV, funding rate (current+history), open interest,
+basis spot/perp, indicatori tecnici. **Nuovi**: `get_orderbook_imbalance`,
+`get_basis_term_structure`.
+
+### Macro
+Treasury yields, FRED indicators, equity futures, asset prices, calendar.
+**Nuovi**: `get_yield_curve_slope` (slope 2y10y/5y30y + butterfly + regime),

+
+### Sentiment
+News (CryptoPanic/CoinDesk), social (LunarCrush), funding multi-exchange,
+OI history. **Nuovi**: `get_funding_arb_spread` (opportunità arb compatte),
