Elephant Memory 0.3.0

Ranked recall returns dated source passages and adds bounded automatic context. Query expansion keeps the original query on failure and forwards cancellation. The Endless preset enables an incremental decision journal with durable batches, restart recovery and source-change invalidation. Coding, raw search and zoom tools remain available. Recall rows open, close and preserve their content after reload. This version supports harness 0.2.1-alpha.1 or newer, below 0.3.
