Interactively generate source images (and optionally short videos) for a herm eikon avatar, iterate on them with the user, and land them under ~/.hermes/eikons/<name>/source/ so the Eikon Studio tab can tune and bake them. This is the agent-driven counterpart to Studio's one-shot Generate dialog.
Guide the user through making or editing a herm sidebar avatar (eikon) using herm's built-in Eikon Studio tab. The agent's role is advisory (what makes a good source, which knob to reach for); source generation is /eikon-create and all rasterize/bake happens in-app.
