/**
 * Invalidate `filePath` and every transitive importer.
 *
 * BFS up the reverse-import graph; for each visited file we (1) drop
 * its transform cache so the next request re-transpiles, and (2) bump
 * its invalidation version so `srcUrl()` emits a fresh `?v=` token —
 * forcing the browser to refetch even when the importer's mtime is
 * unchanged. Bumping versions on transitive importers (not just the
 * originally-changed file) is the load-bearing piece: without it, a
 * page that imports a service via two intermediate components keeps
 * resolving the page module under its old `?v=`, the page bundle's
 * internal `/@src/` references stay pointed at stale URLs, and rapid
 * HMR cycles wedge the browser bundle until the dev server restarts.
 *
 * Cycles are tolerated via the `visited` set.
