Rename the application, Go module path, command package, build artifacts, resource script, and embedded icon assets from PySentry/pysentry to GoSentry/gosentry.
Move portable settings to gosentry.yaml while reading legacy pysentry.yaml during the transition, then rewrite settings under the new name.
Update Windows and Linux autostart integration to use GoSentry names while cleaning up legacy PySentry registry, desktop-entry, and systemd artifacts.
Refresh README, architecture notes, roadmap, changelog, and release examples for version 0.3.0.
Add a shared --start-in-tray argument that lets autostart start the scheduler and tray integration without opening the main window.
Write the argument into Windows Startup shortcuts and Linux XDG Autostart desktop entries, and verify existing autostart entries include it.
Keep manual launches unchanged and let a manual second launch reveal an already-running instance while duplicate autostart launches stay hidden.
