v0.2.3

• Smoother launcher interactions, including improved alphabet drag filtering, icon focus, and looping page changes.
• Faster launcher response with background app indexing, reduced startup work, and less UI-thread search/load churn.
• Safer app behavior by removing the fork-only native loader entrypoint and replacing public restart broadcasts with authenticated restart handling.
• Better LauncherCtl and Shizuku workflows, including launcherctl tty-exec, tty-doctor, and improved restart support in the companion tooling.
