Relaxed generic constraints for job scheduling/execution to allow reference types (removed struct requirement). Updated IJob, IJobParallelFor, and IJobParallel extension methods to support both value and reference types, introducing RunRef for struct-specific overloads. Adjusted JobExecutor and JobScheduler to match new constraints. Bumped assembly version to 3.1.1. Added Value property to Wrapper<T> for ref access and inlined Get(). Changed GGXMipGenerationJob sample count to linear roughness. Removed unused usings in JobInfo.cs.
Replaces unsafe pointer-based job data with JobDataPool<T> and ConcurrentSlotMap<T> for safer, type-safe management. JobInfo now references job data by (dataID, dataGeneration). JobExecutor and JobScheduler updated to use the new pool-based approach, requiring T : struct. Removed FreeList and pointer logic. WorkerThread now uses reference counting to prevent use-after-free. Updated all scheduling APIs and benchmarks to match new signatures. Improved documentation and inlining. Bumped assembly version to 3.0.0 due to breaking changes.
