- ui.js: mount() now wraps non-node children in text nodes (like h()), so
mount(el, "") no longer throws in appendChild — this is what broke the
"Add model" form (applyDefaults cleared a status via mount(x,"")).
- probe_model: resolve managed local models too (they are synthesized into the
registry, not [[models]]) — probing them no longer returns "model not found".
- models.js: await reload() after delete so the row is removed immediately.
