BermudanOption

Bermudan option shell: the exercise-schedule machinery, with a pluggable ContinuationValue. The path is walked once; at each exercise date a smoothed decision compares the immediate exercise value to the estimated continuation value and moves the not-yet-exercised probability mass.

With the default EUROPEAN the continuation estimate is zero, so exercise only ever happens at the last date and the price collapses to the European. A least-squares Monte-Carlo continuation estimator — replay to collect path states, regress on the host, replay again with the fitted continuation as setInput — is Phase 3; it plugs in here without touching this class.
