Smoother sign-in and steadier Cleaner results

Fewer stale sign-in states, Cleaner totals that match their results, and Windows checks that hold up across more systems.

• Sign-in gives clearer messages when your email still needs verification or your account does not have beta access yet.
• Beta sign-up and session refresh handling are more reliable, preventing stale or broken sign-in states.
• Junk Cleaner scans behave more consistently: cancellation is more stable, and the header totals match results accurately.
• Optimizer detects Sleep Study support more accurately and explains unsupported results more clearly.
• NTFS optimization verification is more reliable on systems where different drives report settings differently.
• CPU usage is lower when eclean is opened and minimized to the tray.
