chore: release 0.4.00.4

The web client speaks ten languages instead of one: French, Spanish,
Brazilian Portuguese, Simplified Chinese, Japanese, German, Italian, Dutch
and Polish, all formal, with `hub`, `node` and `GEK` deliberately left in
English so the interface still matches the CLI and the docs. Catalogues
are fetched per language rather than shipped together, plural forms go
through Intl.PluralRules because Polish needs four of them, and locale
matching keeps the region so pt-BR and zh-CN resolve to the files written
for them.

Splitting one module into a loader and ten catalogues gave the SPA a
version dependency it did not have before, and the hub was serving static
assets with no explicit freshness at all. A browser that cached half a
deploy either rendered every string as its own key or, in the other
direction, failed to link the module graph and showed nothing. Static
responses now carry no-cache, which costs one conditional request and
answers 304 with no body.

The node and common packages carry no functional change; they move with
the version because the three are released together.
