The Apple and Android clients are moving onto the canonical
ui.card_overlays key (silo-apple#118, silo-android#158), so the
manifest's advisory platforms metadata now lists them alongside web.
Revision bumped to 4; Go/TS bindings and the conformance fixture
regenerated. Client-repo bindings will pick the bump up on their next
`make settings-bindings` run — nothing else in the manifest changed.
Also stops the web client from erasing the two schema-legal ribbon ids
it does not render yet: buildItems() rebuilt `items` from the web
registry alone, so a stored `imdb_top_250` / `rt_certified_fresh`
config (authorable from Android's native editor, and valid per
card-overlays.json) vanished from both `items` and `order` on the next
web save. Those ids now pass through parse/serialize untouched, on the
same defaults the native registries use, while remaining invisible to
web rendering and settings.
