feat(renderer): smooth shadow sun direction transitions using quantized directions and slerp

Introduce user-controllable shader on/off, shadow mode (rotated Poisson disk, 3x3 grid, or off), light cull face, and discard transparent in depth pass. Expose all settings in new dev panel "shader" tab. Move ambient strength slider to the new tab.
