Fix window positioning for tiling window managers

[stylebending]

Problem

When using tiling window managers like GlazeWM, the bongo cat window was invincible or appeared briefly then disappeared. This happens because FindWindow("Shell_TrayWnd") returns zeros instead of the actual taskbar position.

Solution

• Added fallback logic that detects when taskbar position is invalid (0,0,0,0)
• Uses SystemParametersInfo(SPI_GETWORKAREA) to get screen work area instead
• Applied fix in three places: startup, config reload, and monitor loop
• Also fixed window visibility on startup and cached fullscreen check to prevent race conditions

Testing

• Tested on Windows 11 with GlazeWM
• Cat now appears and stays visible in bottom-right corner
