Add compressed self-serve OTA and resilient native USB sleep

Use a bounded uzlib-derived block encoder with the existing strict tinf decoder, qualify infrastructure roles, budget temporary RAM, and cache running-image metadata. Add self-serve CLI and policy, USB host-loss sleep grace, hardware test harnesses, regression tests, and CI coverage.
