fetch() only retrieves the manifest if needed, doesn't it?
I don't see how this actually pulls content. The code before the original progress bar changed looked like:
guard let img = try? await ClientImage.pull(reference: ref, platform: platform) else {
return try await ClientImage.fetch(reference: ref, platform: platform)

The original code was backwards. fetch() tries to get the image from the local cache first, and if not found, it calls pull().

- Fixes apple#883. Changes `BuildImageResolver` to use `fetch()` instead of `pull()`. `fetch()` checks the cache first and only pulls if needed, preventing incorrect progress events (e.g., "1/1 KB" metadata checks) on cached images that caused the progress bar width calculation to produce negative/weird padding counts, triggering "Fatal error: Negative count not allowed" crashes during rebuilds.
