fix: use profile parameter for MIME type instead of suffix (#75)

Browse source 
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.

Fixes #59
