ZachFix v0.2.6

This is a maintenance release focused on timing, legacy input stability, startup behavior, and D3D9 reset compatibility.

Fixed the vanilla long-session QPC/x87 precision failure by running the affected native timer helpers in scoped x87 PC53 and restoring the caller's precision state afterward.
Fixed pathological legacy WinMM polling where repeated JOYERR_PARMS results could cause DirectInput registry-handle growth, high kernel CPU usage, and severe FPS loss. Affected joystick slots are now suppressed until device configuration changes and are then revalidated.
Added a runtime Skip Intro patch for verified Steam 1.01b and GOG builds. The game executable is not modified on disk.
Fixed windowed D3D9 Reset handling by forcing stale fullscreen refresh-rate values to 0, matching the D3D9 windowed presentation contract.

Clarified the experimental Aim FPU Precision Fix documentation. The scoped PC24 workaround is known to correct the affected aiming behavior, but the underlying trigger/root cause remains unidentified, so the fix remains disabled by default.

Added guidance for using an external 4 GB / Large Address Aware patch where appropriate.

This release remains part of the conservative 0.2.x maintenance line.
