Workstream D: a shared top bar for the SDC tool suite — app name (left), API
settings cog, and the suite app directory (grid) — composed on the existing
TopBar. Adds an ApiSettings dialog and sdc_api_key/sdc_api_endpoint credential
helpers (shared once across all tools, with legacy-key migration). lucide-react
becomes a peer dependency. Bump to 0.2.0.
