Avisynth+ v3.7.6pre-r4403 test build

20251225 3.7.5.r4403 (pre 3.7.6)

• Fix: The Animate() function now explicitly clamps interpolated values to ensure they remain
  strictly between the start and end range. Due to the high precision of 64-bit double introduced
  in v3.7.5, intermediate calculations could slightly exceed the boundary (e.g., 360.00000000000006
  when interpolating from 0 to 360.0 in 564 steps), requiring this clamp to prevent out-of-range errors.
