Dev MCP settings page now recommends Quarkus Agent MCP

[phillip-kruger]

The Dev MCP settings page in Dev UI previously showed how to connect coding agents directly to the Dev MCP HTTP endpoint on the running app. With the quarkus-agent-mcp now available as a standalone project, this is no longer the recommended approach.

The page now has two sections:

• Quarkus Agent MCP (primary) — shows configuration snippets for 9 agents/IDEs (Claude Code, Cursor, VS Code, Claude Desktop, Cline, Goose, Windsurf, Zed, JetBrains) using jbang quarkus-agent-mcp@quarkusio via stdio. Includes a JBang prerequisite note. This section is always visible regardless of whether Dev MCP is enabled.

• Dev MCP Server (secondary) — shows the enable/disable toggle, connected clients, and a collapsible "Advanced: Direct connection" panel with the URL-based configs for connecting directly to the running app's Dev MCP endpoint.
