Black-Scholes theoretical price and Greeks for a REAL, live Deribit BTC/ETH option instrument: pulls that instrument's own spot, strike, days to expiry, and implied volatility from Deribit, then reports how far Deribit's actual quoted mark price sits from what Black-Scholes implies at that IV (priceDiscrepancyPct). This is the trust-check tool: "is this exchange's quoted price consistent with its own volatility assumption?", not an estimate, a live formula cross-check. Use when user gives a specific instrument name (e.g. "BTC-27FEB27-90000-C") and asks "is this option fairly priced?" or "what are the Greeks on this contract?". Returns everything workflow.run_black_scholes does, plus instrumentName, currency, optionType, deribitMarkPriceCoin, deribitMarkIvPct, bsPriceCoin, priceDiscrepancyPct, available (false + error if the instrument name doesn't resolve).
