SPMD SIMD math library & lock-free job system integration

- Add new SPMD SIMD math project with scalar/vector lanes
- Integrate SPMD jobs and scheduling into job system
- Implement lock-free job dependency management
- Update math functions for .NET 10 and SIMD performance
- Add SPMD benchmarks, compress-store tests, and race tests
- Introduce generic Result<T> error handling utilities
- Solution/project file updates and code cleanup
