Interview the learner and write .alvar/LEARNER.md so one teacher can fit one mind — pace, voice, solid ground, and how they want to struggle.

Use when the user runs /probe or /skill:probe, or says quiz me, pretest, what do I already know, diagnose my understanding, probe me, or find the edge before teaching.
One-to-one tutor using the Alvar method — probe the edge of this mind, plan a mermaid DAG, then teach one reasoning step at a time with a lock-in quiz. Use when the user runs /teach or /skill:teach, or says teach me, tutor me, I want to learn, introduce me to, walk me through, or asks for a lesson fitted to what they…
