Strip the transitional node-state classes (2026-09-08)

Browse Source 
The five-class NodeStateClass (taught/known/missed/dont-know/candidate)
was transitional scaffelage from the 2026-09-02 redesign, deriving state
by latest-quiz-wins — exactly what the philosophy rejects: understanding
is inferred at read time from the real state model (still pending
ideation), never encoded as quiz-derived classes.

- contracts: NodeStateClass deleted; GraphSnapshot no longer carries
  nodeStates (objective graph + sessions only).
- core: deriveNodeStates replaced by latestQuizOutcomes — the raw
  event fact (nodeId -> latest quiz kind), consumed ONLY by the
  teacher's graph-as-context selection, never by the home renderer.
- graph-context: hotspot selection re-keyed to outcomes — groups are
  now 'Hotspots (last answer wrong or don-t-know) / Answered correctly /
  Never probed'. Same diagnostic selection, no state taxonomy.
- graph-view: nodes render uniformly (accent color, size 8); the panel
  is search-only; the detail card's state badge is gone. Quiz outcomes
  remain ledger data for the future state model.

Verified live (headless): uniform discs (single color/size, zero state
pixels), search-only panel, card = name + statement + sessions, no
console errors.
