Add OPENWA_HEADLESS=1 mode that hooks user32!MessageBoxA/W via MinHook
to auto-dismiss all message boxes, enabling fully unattended /getlog
replay processing.
Add named event synchronization (OpenWA_HooksReady) between the launcher
and DLL: launcher creates the event before injection, DLL signals it
after install_all() completes, launcher waits before ResumeThread. This
eliminates the race between hook installation and main thread startup.
Add bots_expected.log as golden reference for headless replay log diff
testing.
