When no agent is selected, `e` / `p` do nothing (status line shows "no agent selected") rather than falling back to today's global discover-and-prompt. The discover-and-prompt scaffolding in `_operator_edit_routes_flow` / `_operator_edit_allowlist_flow` comes out entirely — selection in the agents pane is now the only way to scope an edit. Old open-question #4 (single-bottle shortcut behavior in proposals-pane mode) is moot and removed.
