Affected packages with a vitest config now run `vitest run --changed <base>`
(only tests in the changed files' module graph) under the tight "changed"
watchdog, instead of each package's ENTIRE suite under a 60-min backstop.
Packages without a vitest config fall back to their full `test` script. The
curated gate suite still runs as the cross-cutting safety net.
Measured: a dashboard hub-component change drops from 822 files (5-8min) to
40 files (~98s wall incl. gate). Common/leaf changes scope to far fewer.
NOT yet <60s for hub-component changes — the fixed jsdom/setup floor still
dominates (needs the overhead-reduction follow-up), and one scoped-run test
failure needs isolation triage before this gates verification.
