Reset the walk band for a fresh run.

Clears the memo unconditionally: its keys compare image handles, which proxy for content only within one walk. Across runs the caller's input and the contexts' output images are reused in place, so an equal handle does not mean equal pixels.

Retained cross-run state is dropped only when the geometry changes, since surviving between runs is what it is for.
