Keep the shared partial lock, representation-bound resume, connection cap,
and atomic destination publication. Add whole-plan progress and caller-owned
pause events without restoring the old mtime-only garbage collector.
Adapt incoming tests to the surviving partial-state owner and accurate HTTP
range responses. Real native CUDA installation paused, resumed, verified the
pinned archives, and executed the installed binary.
The desktop tests, renderer typecheck, lint, PM tests and local-runtime tests
ran against the integrated paths. No package release or channel write ran.
