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.
