training/producers: move out of dashboard/ per ownership boundary

Producers are event *sources* — the renderer is everything inside
training/dashboard/. Sibling layout makes the dependency direction
one-way (producers import from training.dashboard.events; dashboard
never reaches into producers).

  training/dashboard/producers/   →   training/producers/

Internal imports rewritten via sed; eval_/run.py and training/README.md
cross-references updated. CLI entry stays via `python -m training.producers.<sub>`
(replay / metrics / perf / profiles).
