Preserve logical memoryview descriptors across interpreter transfers, make channel-end release idempotent, and scope runtime-owned interpreter cleanup to the creating top-level runtime. Re-read owned interpreters during shutdown so finalizers cannot leave newly-created children behind. Add regression coverage for sliced and cast memoryviews, repeated channel release, and multiple embedded runtimes. Assisted-by: Codex:GPT-5
