feat: complete wrtd binary compilation success

All major compilation blockers resolved:
- SIMD syntax errors fixed (5 locations)
- StacklessEngine API compatibility restored
- Memory provider consistency established
- KANI setup and verification working
- wrtd binary now compiles successfully

This resolves months of circular compilation issues and enables
full WebAssembly runtime daemon functionality.
