fix: force the Storybook dep pre-bundle on every run instead of trusting the cache

Vite keys the Storybook project's dep cache on the lockfile and the config,
never on what the story graph imports. After a story or component gains an
import of an already-installed package, the cached bundle is still "valid",
Vite skips the scan, and the first request for the new package re-runs the
optimizer mid-run: the browser hash is bumped, a full-reload is sent that the
Vitest tester iframes ignore, and the `@storybook/react` renderer already
loaded in a live iframe keeps the old `?v=` for its lazy
`import("@storybook/react-dom-shim")`, so every story that iframe renders from
then on fails with "Failed to fetch dynamically imported module". The next run
is green because the cache has caught up.

`optimizeDeps.force: true` on the storybook project discards the cache up
front so the scanner crawls every story entry before the browser opens — the
cold path CI already takes on every PR. Measured: stale-cache 6/6 red on the
baseline, 6/6 green with the fix, 3/3 red reverted; ~0.8s per run.

Closes #2340
