🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Refresh the right-sidebar settings when feature gates change
rightSidebarTabsUpdates() does not observe Feed, Dock, or Cloud Machines gate changes. rightSidebarTabItems() reads those gates through RightSidebarMode.availableModes(), while the feature toggles write UserDefaults directly. If a gate changes while SidebarSection is open, the card can retain a disabled tab or omit an enabled tab until another observed change occurs. Emit or observe a feature-availability update and yield fresh items.

Use scoped owners or private/fileprivate helpers for the new static behavior.
RightSidebarTabPreferences can create an ambient persistence owner through UserDefaults.standard and NotificationCenter.default. Replace it with an injectable RightSidebarTabPreferenceStore, and pass it to its consumers. Make RightSidebarModeDragPayload an instance-owned value with only its UTI constants static. Replace the internal static RightSidebarModeBarReorderPolicy namespace with a private/fileprivate helper because its reorder logic is pure.

With Feed and Dock feature-gated off, Cloud is the 4th visible tab in the right sidebar's mode bar, but ctrl+4 was pinned to the invisible Feed and did nothing while Cloud answered only ctrl+6. The new test presses ctrl+4 in that configuration and expects the Cloud (machines) tab. Also pins the mode gates and tab preferences in the existing digit-default tests so the test host's own settings cannot shift the expected digits.
The ctrl+digit mode shortcuts now default to the mode's position among the VISIBLE tabs instead of a fixed per-mode table. With Feed and Dock hidden, Cloud is the 4th tab and answers ctrl+4 (it was pinned to ctrl+6 while ctrl+4 fell on the invisible Feed and did nothing). Explicit user bindings still win, hints and Settings show the resolved values, and CmuxSettings gets a host-installed default-stroke override so the package's effective-shortcut resolution agrees with the app. Tabs are now user-customizable: a Right Sidebar Tabs card in Settings > Sidebar (visibility toggles, reorder arrows, live shortcut labels) and a right-click menu on the mode bar (show/hide plus a jump to that card). Preferences live in rightSidebar.tabs.order / rightSidebar.tabs.hidden; hiding the last visible tab is refused. Explicit selection of a hidden tab (CLI, palette, notification routing) still works and reveals the tab while it is active; restore and preference changes re-land on a visible tab. Also adds the missing setting:betaFeatures:cloudMachines anchor to the package's reachability mirror list (pre-existing red test on main).
…e provider The KeyboardShortcutSettingsObserver.shared @State stored property builds its matcher snapshot before cmuxApp's init body runs, so the right-sidebar digit entries were cached from the builtin table and ctrl+4 still fell on the invisible Feed. Posting the standard shortcut-settings change notification after installing the provider rebuilds those snapshots against the positional defaults.
Each pill is draggable (in-process custom UTI, declared in Info.plist like the workspace-tab reorder type). Hovering another pill commits the new order through RightSidebarTabPreferences.setDisplayedOrder, which permutes only the displayed tabs' slots so hidden tabs keep their place, and the existing change notification re-renders the bar and shifts the ctrl+digit defaults with the tabs.

Mark the new value-model struct nonisolated.
RightSidebarTabSettingsItem is a pure Sendable value struct with only String/Bool members. Mark it nonisolated so it is not implicitly @MainActor-isolated.
As per coding guidelines: "In Swift 6, mark Codable, Identifiable, Sendable, and pure value-model structs as nonisolated when they should not be implicitly @MainActor-isolated."

Since manaflow-ai#11950 the Control-digit defaults for right sidebar tabs are positional over the visible tabs, and a hidden or unavailable tab gets no default. Feed and Dock are off unless their beta settings are on, so on a host without those settings `testRightSidebarModeSwitchesHavePrivateControlDigitDefaults` sees an unbound shortcut where it expects Control-4 and Control-5. Turn Feed and Dock on and clear the tab order and hidden-tab settings for the duration of the test, restoring them afterwards, the way `RightSidebarModeShortcutHintTests` already does.
