feat: show views as the live globe in MCP Apps clients

show_on_globe replaces open_in_gods_eye_view and names an MCP Apps view, a
ui:// panel that loads the app in embed mode and posts each later view to it,
so the globe in the conversation changes without reloading. It also takes a
view another answer returned. Tools can declare a UI resource, and the MCP
adapter serves resources/list and resources/read and lists each tool's
resource in _meta.ui.resourceUri.
