chore: remove kbx-foundation-v36 reference (superseded by v4 implementation)

Removed entire kbx-foundation-v36 directory as it's been replaced by
the new KBX Foundation v4 patterns implemented in this session:
- Registry-driven screen definitions
- Density-aware UI adapter components
- Feature module templates (ShadowRun, Models)
