Description:
Create a time of day controller that updates sun position, atmospheric parameters, and lighting.
Tasks:

Create TimeOfDay struct with current time (0-24 hours)
Calculate sun position from time (azimuth and elevation)
Update directional light direction based on sun
Update sun color based on atmospheric scattering
Add time progression (automatic or manual)
Update atmosphere shader parameters from time
Add debug UI for time control
Test full day/night cycle

Acceptance Criteria:

Sun moves across sky realistically
Light direction updates with sun position
Sky colors transition naturally through day
Can manually control time for testing

Related Issues: Depends on #20
Estimated Time: 2-3 days
