Flattener<T> class

Owns the flat-list cache and the incremental-vs-rebuild decision.

The caller pushes the current inputs each build via update; the Flattener projects the input for the ViewMode (see ViewModeProjection), flattens it, and decides whether a single-node change can be applied incrementally or a full rebuild is required. It reads caller-owned state (the Expanded Set) but never mutates it (ADR-0002).
