/**
 * Vitest global setup — ADR-125 Phase 7 (RuVector boundary cleanup).
 *
 * The agentdb / @ruvector/rvf native bindings write a `ruvector.db` redb file
 * to the package's cwd as a side-effect of any code path that touches the
 * vector store. The file is test pollution — it has no source reference in
 * `src/**` and recreates itself on demand. This setup file wipes it before
 * and after the test run so each fresh test session starts from a known state
 * and CI smokes do not see stray DB files in `git status` after `npm test`.
 *
 * Wired into `vitest.config.ts` via `setupFiles: ['./vitest.setup.ts']`.
 *
 * @see ../../docs/adr/ADR-125-memory-consolidation.md Phase 7.
