feat(snapshot): add CaptureHealth to surface partial capture state
Adds CaptureHealth{FailedSteps, Partial} to Snapshot. captureBrewList now propagates brew errors instead of swallowing them. CaptureWithProgress collects failed step names unconditionally (not gated on callback) and writes them to snap.Health. captureWithUI warns the user before save/upload when the snapshot is partial. Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai>
