/**
 * The completion brain: (document text, cursor) → autocomplete items.
 *
 * Pure and dependency-free. Cursor context is derived from lightweight text
 * heuristics on the characters before the caret — robust while the document
 * is half-typed and invalid (a full parse would often fail). Dynamic lists
 * that DO need the document (sequence names for `parent=`) come from a
 * simple regex scan, not a parse, for the same robustness.
 *
 * Contexts detected:
 *   - `<` (+ partial)            → tag names
 *   - `<tag …·`                  → that tag's attribute names
 *   - `attr="·`                  → values for that attribute:
 *       type="·"     → generator types
 *       value="·"    → template paths + pack addresses
 *       parent="·"   → declared sequence names
 *       alphabet="·" → alphabet names
