emil28092005 46a04850e3 fix: rendering now works — three critical bugs fixed ...

1. VkColorComponentFlags: wrong bit values (0x10-0x80 instead of 0x01-0x08)
   → colorWriteMask was 0xF0 instead of 0x0F → no color channels written

2. VkClearValue: was Sequential layout instead of Explicit (union)
   → depthStencil clear value written at wrong offset → depth buffer
   cleared to 0.0 instead of 1.0 → all fragments failed depth test

3. Vulkan clip space correction in vertex shader:
   gl_Position.y = -gl_Position.y (Vulkan Y-down vs OpenGL Y-up)
   gl_Position.z = (gl_Position.z + gl_Position.w) * 0.5 (Z [0,1] vs [-1,1])

Also:
- PushConstantSize fixed from 128 to 144 (two mat4 + vec4)
- Dynamic viewport/scissor state added to pipeline
- Push constants use column_major (default) to match System.Numerics row-major layout
- Camera.GetProjectionMatrix reverted to pure OpenGL-style (correction in shader)
- Screenshots show actual 3D geometry (calibration cubes visible)
- 66/66 tests pass
