- Replaced the original R6 prototype with an idiomatic functional
pricing API.

puts.
- Added European Monte Carlo pricing with antithetic and control
variates.
- Added Monte Carlo standard errors, confidence intervals, and
diagnostics.
- Added risk-neutral geometric Brownian motion path simulation.

helpers.
- Added generic finite-difference delta, gamma, vega, rho, and
theta.
