Function supportsContentMimeType

supportsContentMimeType(
contentMimeTypes: string[] | undefined,
mimeType: string,
): boolean
Check whether a payload MIME type is included in a set of supported dynamic content MIME types, honoring the ["*"] wildcard.

Servers use this against the host's negotiated contentMimeTypes extension setting before registering renderer-pattern tools; hosts can use it against a view's declared contentMimeTypes to type-filter payloads.
Parameters
- contentMimeTypes: string[] | undefined
- mimeType: string
Returns boolean
Example
```
// Server: register the renderer-pattern tool only when the host
// forwards this payload type (handles the ["*"] wildcard)
if (supportsContentMimeType(uiCap?.contentMimeTypes, A2UI_MIME_TYPE)) {
  // register tool returning marked A2UI payloads
} else {
  // register text-only or structuredContent-driven variant
}
```
