The token card's corner already carries the session's cache-hit share
(ef72a7b), so the Context Stats board duplicated it. The grid is now six
cells: turns, steps, human inputs, live tool calls, and the two cost cells.
The removal takes its dead plumbing with it — the card drops its `usage`
prop, and `cacheHitPercent` loses the `decimals` override that existed only
for this cell's one-decimal display. The README rows and the card's
screenshot move the figure to the token card.
