Auto-provisioned agents (via the research + loops team wizard) show
up on the Agents page (same agents::insert → agents::roster path),
and PATCH /api/claws/{id} already handled name/job_title/system_prompt/
avatar/accent/wallpaper. The one thing that was NOT reachable from the
Agents page: swapping the model.
Add a dedicated endpoint:
- PATCH /api/claws/{id}/model { model: string }
- Persists via agents::set_model_binding (DB)
- Best-effort runtime rebind via RuntimeProvisioner::provision_claw
(idempotent — overwrites agents.<alias>.model_provider on the
shared ZeroClaw config)
- Audit-logged as 'agent.model_changed' with the new model in payload
Now an operator can open the Agents page, click a claw that was
auto-provisioned by the team wizard, and swap its model
(claude-sonnet-5 → glm-5.2 → whatever) without recreating the team.
Same DB row, same claw_id, same brain — just a new provider on the
next turn.
Frontend affordance not shipped in this commit — the endpoint is
usable via curl/psql/scripts today; a UI 'Model' picker on the claw
detail card can land in the next Agents-page pass.
