feat(check): score fix, break, efficiency and speed in one block

kvb-check-efficiency measures a change against its base: tokens.py counts skill text tokens and listing words, measure.py runs one command in a base worktree and the working tree (one run per side, the mean of five over 100, an estimate marked ~ when other processes load the CPU). kvb-check-speed reads wall time from the same run and is not relevant for skills. kvb-check-score prints fix, break, efficiency, speed and the product score with emojis plus a gate line: below 90/5 it reports, over 100 it requires asking the operator before the commit.

Every skill that reported confidence and break risk now shows the score block; the 90/5 bar adds efficiency and speed at most 100. Commit blocks and the commit call's approval prompt name worktree, branch, diff stat and the score values, also for merges. 24 descriptions were shortened to keep the skill listing within its budget.
