`Nuxt MCP Toolkit` adds support for MCP apps

Agent tools can now return inline interactive HTML, not just text. Useful for richer tool flows inside Claude or ChatGPT.

• —Tools declared with defineMcpApp can render interactive HTML responses in MCP clients such as Claude and ChatGPT.
• —useMcpApp lets the UI read pre-hydrated data, trigger follow-up prompts, or call other tools from inside the response.
• —Vue SFCs are bundled into self-contained HTML at build time and served from the MCP endpoint, reducing custom UI plumbing.
