jgrusewski d0227e78bb docs: fix 6 issues in IQL integration spec from code review ...

- Fix staleness: buffer_write_pos is host-side, pass as scalar (not in GpuBatch)
- Fix epsilon: branching_action_select takes 3 scalar epsilons, not 1
- Fix dead code list: add GpuExperienceCollector::v_range_ptr, FusedTrainingCtx wrappers, training_loop callers
- Fix step 0: seed per_sample_support with [-1, 1] default at construction
- Fix entropy: delete ent_scale conditionals, branch_scales subsumes them
- Fix non-graph c51 launches: 4 sites in gpu_dqn_trainer.rs need per_sample_support
