Subject: [PATCH] fix: Add explicit @intCast for u16 to i16 mouse coordinate
 conversions

Zig 0.15 requires explicit integer casts where implicit conversions were
previously allowed. When assigning Point.col/row (u16) to Mouse.col/row
(i16), an explicit @intCast is now required.

This fixes compilation errors in vxfw.App.MouseHandler.handleMouse when
building with Zig 0.15.
