Add bbox cache subcommand for image cache management#88
Merged
Conversation
Add `bbox cache` with three subcommands: - `bbox cache list` — show cached images with digest, size, last-used time, and which image refs point to each entry - `bbox cache gc` — remove rootfs entries not referenced by any image ref (supports --dry-run) - `bbox cache purge` — remove the entire cache directory (requires --force or interactive confirmation) Bump go-microvm to v0.0.25 which adds the List, GC, and Purge methods to image.Cache.

v0.0.26 fixes legacy ref files showing as orphans in cache list and gc --dry-run incorrectly reporting referenced entries as removable. Also fixes errcheck lint warnings in cache.go. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
