The gnubok_connect_bank and gnubok_connect_skatteverket tools now carry
definition-level _meta.ui.resourceUri pointing at a new connect-card MCP
Apps widget. On claude.ai/Claude Desktop the tool result renders as a card
with an "Öppna i webbläsaren" button that sends the host a ui/open-link
request from the click handler (the sanctioned new-tab mechanism; custom
connectors always get Claude's confirmation modal, so the destination URL
is shown in the card). Clients that do not render MCP Apps (Claude Code)
keep the connect_url in the structured result as before.
