release(v1.6.0-alpha): smoke-test release for system-update flow

No functional changes from v1.5.0-alpha — this release exists only to
validate the in-app update pipeline end-to-end (manifest check → staged
download → apply → restart → version bump in UI sidebar).

Dropping just the manifest + artifacts; no manual deploy to the fleet.
.116/.228/.253 should notice within 30 min (periodic update-check
interval) and surface the update in the dashboard.
