/**
 * Component completion audit.
 *
 * Walks every UIX component (morfo + eidos wrapper + recipe CSS + demo)
 * and scores it against the rules in
 * `src/uix/COMPONENT_COMPLETION_CHECKLIST.md`.
 *
 * Output: `tmp/component-audit.md` — markdown report with summary table
 *  + per-component findings.
 *
 * Usage:
 *   node --import tsx/esm scripts/component-audit.ts
 *   node --import tsx/esm scripts/component-audit.ts --only rating-group,calendar
 *   node --import tsx/esm scripts/component-audit.ts --severity error
 *
 * Approach: text/regex parsing of source files. Doesn't dynamically import
 * morfos (avoids full TS resolution + circular dep risk). The morfo files
 * are declarative `as const satisfies Morfo` exports, so regex catches
 * the structural facts we need. Cross-validation against canonical
 * vocabularies via static imports of `INTENTS`, `SEMA_FAMILIES`,
 * `SEMA_VERBS`, `ARCHETYPE_VOCABULARY`.
