What is new in Contained 1.0.0-nightly.235+00b298b

Automated build of `nightly` @ 00b298b.

## Changes Since Last Nightly

- Added **Free Up Space…** with compaction selected by default, explicit opt-in resource/cache deletion, and access to automatic compaction settings.
- Fixed Apple Container recreation accumulating image entrypoint arguments; pinned and verified rollback, preserved originals before update pulls without weakening child-manifest digest pins, and added visible recovery for missing containers after failed replacement/restoration.
- Protected saved recovery and local metadata during failed runtime reads, corrupt-data recovery, and orphan cleanup; kept stopped originals stopped during restoration, kept open resource details current, and reduced repeated cleanup scans and scrolling work.

## Full Release Notes

### Highlights

- First complete Contained release: a native macOS 26 SwiftUI control surface for Apple's `container` CLI.
- Classic sidebar navigation is the default experience. The Liquid Glass toolbar, morph panels, command palette, Docker Hub search, Compose import, image build workspace, and keyboard shortcuts are available as explicit experimental features.
- Contained stays CLI-first: privileged runtime work goes through Apple's `container` command, run/edit operations can reveal the generated `container ...` command, and decorative app metadata stays local to Contained.
