fix(dev): proxy content registry to CLI server

Inline spark tables (role=spark-table) live in the content registry, but the
rsbuild dev proxy forwarded only /__COMPLETIONS.json and
/__CONTENT_INDEX.json. The registry fetch fell back to the SPA index.html,
so /roll resolved the inline CSV as HTML and csv-parse failed with an
invalid opening quote.

Load the registry before publishing the loaded completions state so a roll
cannot fire while inline content is still unresolvable.
