The original handoff doc described an empty M0 scaffold with placeholder
screens to "discuss tomorrow". 0.3.1 actually ships the full UI plus
villager trade rebalance, so the doc now is a testing guide for the
working features rather than a discussion-points list.
Includes the architecture diagram for how Java + KubeJS interact, the
key bindings table, a step-by-step testing path, and a known-gaps list
for future iteration.
