Change MIME type from `text/html+mcp` to `text/html;profile=mcp-app` to follow RFC 6838 recommendations for custom media types. The `+suffix` format (like `text/html+mcp`) is intended for structured syntax suffixes (e.g., `+json`, `+xml`) that describe the underlying format. Since MCP Apps doesn't define a new syntax but rather a profile of HTML, using a profile parameter is more semantically correct.

There was a problem hiding this comment.
Note: spaces are allowed before / after the ; and the profile value can be quoted (see spec) so in theory we should test w/ t.match(/text\/html\s*;\s*profile=(mcp-app|"mcp-app")/)
