First-use UX fix: the TUI rendered the daemon list but felt frozen because mode and focus were invisible, and the sidebar had no nav keys, so `Enter`/`AttachHighlighted` had nothing to target. - `render::draw` now reserves the bottom row for a status bar that always shows `[NORMAL]`/`[INSERT]` (cyan/yellow chip), the focused panel (sidebar / pane), and the most useful key hints (`j/k: nav • enter: attach • s: spawn • ?: help • ^Wq: quit`). Status bar is never eclipsed by overlays. - `Sidebar::render_with_focus` and the pane block now draw their border in cyan when focused, in the default colour otherwise. - New `Action::SidebarNext` / `SidebarPrev`, bound to `j`/`k` and `down`/`up` in the shipped Normal-mode defaults. Dispatch walks the catalog's session list, calling `AppState::move_sidebar_highlight` (wraps both ends). Workspace clippy + 85 unit tests + 3 integration tests green.
