Ln 222 Story Replanner

When your Epic requirements shift and you need to realign your Stories without losing work, this replanner compares what you have against what you need and tells you what to keep, update, obsolete, or create. It runs standalone or as part of a coordinated workflow, loads existing Stories from your tracker, applies a classification algorithm, and executes the changes while preserving completed work. The nine phase runtime is thorough, maybe more than you need for small adjustments, but when you're reconciling a dozen Stories against new requirements it beats manual diffing. Ships with auto-approve mode if you trust the algorithm or interactive confirmation if you want control.
