feat(score): cost and time labels, worktree path below the table

Efficiency and speed are after/before ratios where over 100 % is worse, so the labels now read 💸 cost and ⏱️ time in score.py, tokens.py, measure.py, the gate texts, the message block and every skill that quotes them; 💰 stays the value quotient and the --efficiency/--speed flags keep their names. --commit-table drops the worktree column, which took the table's width, and prints the path below it alone in a text block for copy and paste.

🎯 Fix: 94 %
💥 Break: 2 %
💸 Cost: 100 %
⏱️ Time: –
🛡️ Security: 100 %
💰 Value: ?
🏆 Score: 92
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
