v0.0.7

• After a shaky pass, "Teach me this" (⌥X) gives a short lesson from your first error. Your outcome does not change.
• When you say you do not know a term, the next nudge explains it first.
• The grader reads past speech-to-text noise, and judges a restated point with the earlier one.
• The close says your level in plain words: "Not at a level yet. Next review in 12 h."
• The index tick needs pobblebonk 0.0.6, so a quiet tick leaves no empty note.
