20260806

This release focuses on compatibility and protected-mode correctness:

• Fixed 386 task switching used by Bubble Universe.
• Fixed the interrupt shadow after MOV SS and POP SS, preventing
  input-dependent crashes in Settlers II.
• Improved Windows 3.1 compatibility, including precise instruction-fetch page
  faults and the repeated right-edge strip in 1024x768 modes.
• Added BSWAP and corrected several CPU-identification behaviors used by
  HWiNFO's processor errata tests.
• Fixed Rusty's clipped intro framing by showing VGA overscan by default.
