Job graph scheduler: worker threads, dependency tracking and parallel frame execution.

Systems declare a job’s dependencies when adding it to a JobGraph; Scheduler::run derives execution order from that graph rather than the caller hand-sequencing calls, and runs independent branches (see docs/threading-model.md’s shape-of-a-frame example) across worker threads in parallel. Current implementation is a single shared ready-queue behind one mutex, not per-worker lock-free deques — see “Implementation note” on Scheduler for why that’s a deliberate first step, not the final design.

Structs

JobGraph

A dependency-ordered set of jobs for one frame. Build with add_job, then hand to Scheduler::run.

JobId

Opaque handle to a job within the JobGraph it was added to. Not valid across different JobGraphs.

Scheduler

Runs a JobGraph across worker threads, respecting declared dependencies.
