new package location.

Move autostart_*.go and tests from src/core to src/platform/autostart.
Update src/gui/app.go to call autostart.SetAutostart / autostart.AutostartStatus.
Add quoteDesktopExec to desktop_linux.go (was co-located in autostart_linux.go).

Extract the hidden-window logic out of src/core runner and autostart files
into a new platform/winproc package with per-OS build-tag files. All call
sites updated to use winproc.ConfigureHiddenWindow. Builds clean on both
Windows and Linux; all tests pass.
