Add a deployment primitive for non-executable catalog assets that copies a versioned item directory plus manifest to a selected head hard disk. The first target is Turbo at Cloud 7 (turbo-pancake-76, node-adf19775). Preserve original extensions, verify checksums after transfer, use an atomic staging-to-ready transition, and report installed state without requiring kiosk launch automation.
Acceptance: deploy/verify/remove operations are observable; interrupted copies do not appear ready; paths and disk-space behavior are documented.
