Romuald Członkowski	a57b400bd0	fix: use official ext-apps useApp hook to fix blank MCP App rendering (#578 ) The custom useToolData hook had lifecycle issues that prevented the UI from rendering in Claude Desktop/web: no appInfo in App constructor, unhandled connect() Promise, app.close() on unmount conflicting with React Strict Mode. Switched to the official useApp hook from @modelcontextprotocol/ext-apps/react which handles initialization handshake, handler registration, and cleanup correctly.

fix: use official ext-apps useApp hook to fix blank MCP App rendering (#578 )

The custom useToolData hook had lifecycle issues that prevented the UI
from rendering in Claude Desktop/web: no appInfo in App constructor,
unhandled connect() Promise, app.close() on unmount conflicting with
React Strict Mode. Switched to the official useApp hook from
@modelcontextprotocol/ext-apps/react which handles initialization
handshake, handler registration, and cleanup correctly.

fix: use text/html;profile=mcp-app MIME type for MCP Apps resources (#577 )

The ext-apps spec requires RESOURCE_MIME_TYPE (text/html;profile=mcp-app)
for hosts to recognize resources as MCP Apps. Without the profile parameter,
Claude Desktop/web fails with "Failed to load MCP App: the resource may
exceed the 5 MB size limit."
