The strip could only be hidden by an undiscoverable double-tap, and once hidden the zone had no chrome left to click — no tab, no ✕, no menu holding "Show". This puts it on the same footing as the status bar, whose hide has never stranded anyone: ⌥⌘T, a ⌘K row, the shell context menu, and the zone menu, which now prints the keystroke on the row that takes the strip away so the way back is stated at the moment it matters. All four resolve their target zone the same way the other tab verbs do (hovered, else focused, else the workspace) and describe themselves from what is on screen rather than from a stored value, so "toggle" always means the opposite of what the user is looking at. Adds an app-wide default alongside it, in Appearance next to Session List Density — auto, always, or never, matching VS Code's `workbench.editor.showTabs` and Zed's `tab_bar.show` for people who want one answer everywhere instead of a per-zone choice they repeat. A zone that has stated its own preference still wins, and neither value can strand a pane.
