File drop needs a local filesystem to deliver into and a receiver it can bind, so wasm supports neither and never sets a manager. The code still linked in, because the Engine reached filedrop through an untagged field, and with it the net/http server and client. That put the wasm binary 0.97MiB over the 60MB budget, on a main that had 0.34MiB of headroom left. Split the feature on the js tag: the logic file and the OS dialer become !js, a js no-op carries the start, stop and rebind entry points the engine calls on its lifecycle paths, and a build-tagged alias types the manager so engine.go and connect.go stay untagged and lose the import. iOS keeps the full feature: the logic file is !js and the iOS dialer stays behind the ios tag. Drops the wasm binary to 59.89MiB, with no filedrop symbol left in it.
