Consolidate all render formats under ui://. The sentiment from the community is that we should use mimeType to discriminate between types. Currently, mcp-ui still supports raw HTML (text/html) and external URL (text/uri-list), but in the future we'll be able to add arbitrary types in the future.

This PR maintains backwards compatibility on the client side with proper warnings. Support will be removed in MAJOR version 4.

Pull Request Overview

This PR consolidates the resource URI schemes so that all resources now use the ui:// scheme with the mimeType field distinguishing between HTML content and external URL content. Key changes include:

  • Server‑side: Refactored createHtmlResource and updated URI validations/messages.
  • Client‑side: Updated tests, component behavior, and documentation to reflect the new ui:// scheme and mimeType usage.
  • Docs & Examples: Revised code samples and documentation to drop legacy ui-app:// references.
