Disk Cleanup

Automated disk space recovery for OpenClaw deployments. Covers 12 cleanup categories that OpenClaw does not handle natively (as of 2026.3.13).

What OpenClaw Already Handles (skip these)

• Session store: session.maintenance config (pruneAfter, maxEntries, rotateBytes)
• Sandbox containers: sandbox.prune config (idleHours, maxAgeDays)
• Context pruning: contextPruning config (cache-ttl mode)
