/**
 * Navigation + hover brains: hover tooltips, go-to-definition, find-
 * references, and rename for sequence names.
 *
 * Pure and dependency-free, position-based. What's under the caret is
 * resolved by `tokenAt` via text scanning (no parse — robust on half-typed
 * documents), then each feature acts on that token:
 *   - hover      → a short doc for the tag / attribute / sequence reference
 *   - definition → the `<sequence name="X">` declaration for a reference
 *   - references → every place that names sequence X (decl + parent + ${{}})
 *   - rename     → replace exactly the base-name span at each of those places
