Update the SLEEP-IMPLEMENTATION-PLAN.md to reflect Phase J completion: the local libredox fork and local syscall fork are now both in place, the [patch.crates-io] and [patch.'<URL>'] overrides are correctly wired in both the base and kernel workspaces, and the typed-AcpiVerb path (EnterS2Idle / ExitS2Idle) is the primary path. The kstop string-arg path remains as a fallback for older acpid builds. Both paths work end-to-end; the build succeeds; the ISO is produced. Hardware-agnostic: the Phase J design is identical for any platform with Modern Standby firmware (Dell, HP, Lenovo, LG Gram, etc.).
