fix(launch): welcome picker shows mesh name + slug (v1.20.1)

The launch welcome flow's menuSelect was rendering opts.meshes.map(
m => m.slug) — so even after rename writes the new name to local
config, the picker still only showed the slug. Renders as
"name  (slug)" when they differ; falls back to slug alone when
they match (default for never-renamed meshes).
