This PR updates the `SlashCommand` trait to use a streaming return type. This change is just at the trait layer. The goal here is to decouple changing the trait's API while preserving behavior on either side. The `SlashCommandOutput` type now has two methods for converting two and from a stream to use in cases where we're not yet doing streaming. On the `SlashCommand` implementer side, the implements can call `to_event_stream` to produce a stream of events based off the `SlashCommandOutput`. On the slash command consumer side we use `SlashCommandOutput::from_event_stream` to convert a stream of events back into a `SlashCommandOutput`. The `/file` slash command has been updated to emit `SlashCommandEvent`s directly in order for it to work properly. Release Notes: - N/A --------- Co-authored-by: Max <max@zed.dev>
