Fix disk-full errors in VM sandboxes

Free up disk space in Cowork VMs and sandboxes

Resolving 'disk full' errors during long sandbox sessions without restarting the VM.

• · optional: cleanup targets (caches, temp files, old logs)

• · freed disk space in GB
• · breakdown of cleaned categories (docker, temp, caches)

• · sandbox filesystem access
• · Cowork VM manager

running inside Cowork VM or Claude Code sandbox; write access to /tmp and cache directories

cleanup fails if process actively using cache; errors if cleanup process killed mid-run; space reclaimed less than expected if large artifacts created during cleanup

• · Cowork-aware cleanup targets
• · safe-to-delete filtering
• · automatic garbage collection
