Expand description

agent.open, but launching into an existing, empty agent pane ({view:"agent"}, the picker) instead of creating a new one and inserting it into the layout. Used by Layouts → Open layout… (SPEC_LAYOUT_FILES_2026_09_25.md §3.5), which rebuilds the saved split tree first and then launches each agent into its placeholder — so every check agent.open makes (admission, one live instance, provider, CLI, resume, config files) applies unchanged. If the agent is already open in this tab, that pane is returned and the placeholder is left as a picker.
