Subject: [PATCH] fix(search): serve a fresh search index after dev updates

Re-indexing only invalidated the bare @localSearchIndex module; the
per-locale modules that carry the data were still served from the
transform cache, and the browser module cache pinned them too. Version
the locale import in dev so every index update loads fresh data.
