DanSandClaude Opus 4.8 fa1ba97286 perf(win): skip DWM blur/acrylic when the window starts opaque
The window always asked DWM for a full-window blur region and, on
Windows 11, an acrylic backdrop. When the user runs with an opaque
window (low-spec mode or full opacity) that desktop blur is never seen
but DWM still composites it every frame.

- An early read of the saved settings decides whether the window starts
  opaque before the backdrop is configured.
- When it does, the full-window blur region is left as SDL's zero-area
  default and the backdrop type is set to none instead of acrylic.

Windows-only.
