refactor: use MCP resource types for ui/download-file params
Replace custom {filename, content, mimeType, encoding} params with
standard MCP resource types: EmbeddedResource for inline content and
ResourceLink for host-resolved references.
New params shape:
params: { contents: (EmbeddedResource | ResourceLink)[] }
This reuses existing MCP primitives instead of inventing new ones,
and enables hosts to show resource 'bubbles' or resolve ResourceLink
URIs via resources/read on the MCP server.
