fix: exclude Floor and Grid from shadow pass — no more blocked light

Browse Source 
- drawCalls now include castShadow flag (bool)
- Floor and Grid entities: castShadow=false (skip in shadow pass)
- Shadow pass: foreach with 'if (!dc.castShadow) continue;'
- Main pass: renders all objects (floor receives shadows but doesn't cast)
