iaa-template-resource-integration

Integrate reusable image template resources into the IAA repository through the standard resources-to-R.py pipeline. Use when Codex needs to turn a captured image patch into a formal template under `resources/`, add or update a `*.png.json` resource definition, run `tools/make_resources.py`, verify the generated prefab appears in `iaa/tasks/R.py`, or replace ad-hoc image path loading with generated `R.*` references.
