• change: Codebase tune-up: sharper debug trail, snappier renders.
• change: Debug logs now show every screen navigation, so support bundles explain exactly how you got into a state
• change: Cloud sync thread-spawn failures log the underlying OS error instead of a generic "failed to start" toast
• change: Preference-save errors (view mode, sort order) now surface in the debug log instead of being silently dropped
• fix: Remove a theoretical crash path in toast-timeout calculation when a new message class is added
