Oh My OpenAgent 5.1.64 makes desktop memory-sync claims fail closed
Oh My OpenAgent 5.1.64 starts the desktop memory-engine claim before extensions and session initialization, reports the engine unavailable when the claim fails and does not fall back to CLI credentials. It follows the retained signed-download and device-revocation controls on the same release line.
Why it matters: Starting synchronization only after an explicit desktop-engine claim narrows a credential-confusion path where startup ordering or fallback behavior could select a broader identity than the operator intended.
