Fixes #21357.

A custom Ctrl+U binding could open Usage but could not return to the previous page. Both global shortcut handlers omitted usagePageOpen, so the matcher kept selecting usage.open on the Usage page.

Apply the handler patch @kendonB proposed in #21357. Pass the current route state to the navigation-history and command-palette matchers and refresh their listeners when it changes. Default shortcuts stay the same. After merging current main, the browser regression was dropped with its deleted test file because it used DOM events, mocked navigation calls, and fake-timer setup, which the test purge excludes.

Validation:

• After merging main 05696c6, the surviving keybinding and command-palette logic suites pass, 73 tests total. The dropped browser regression no longer supplies automated Linux Ctrl+U or MacIntel Meta+U coverage. The original red/green evidence applies to the pre-purge test only.
• Web typecheck, changed-file lint and formatting, and git diff --check pass.
• Real Linux Chromium keyboard input with the issue's bindings opens Usage and returns to the same thread. The before screenshots use the base handlers and the after screenshots use the first commit; the second commit only changes tests. Native desktop packaging, macOS and mobile were not run.

Before, the second Ctrl+U stays on Usage:

📝 Walkthrough

Both navigation shortcut handlers now provide the current /usage route state to shortcut resolution. Their keyboard handlers refresh when that route state changes.

Changes: Usage Shortcut Route Context

Layer / File(s)	Summary
Pass Usage route state to shortcut handlers apps/web/src/components/AppSidebarLayout.tsx, apps/web/src/components/CommandPalette.tsx	Both handlers pass whether the current route is /usage to shortcut resolution. Their effect dependencies include this route state.

Explanation

PASS. The PR implements the coding requirements in issue #21357. NavigationHistoryShortcuts and CommandPalette derive usagePageOpen from the /usage route and pass it to resolveShortcutCommand(). The handlers refresh when the route state changes. This enables navigation.back on Usage and preserves the default shortcuts. The current description states that the surviving keybinding and command-palette suites pass. The deleted browser regression is not required by the issue criteria.

Mount NavigationHistoryShortcuts and assert the history-back action.

This test renders only CommandPalette. Its second shortcut press checks only that the palette does not navigate. It does not verify that NavigationHistoryShortcuts calls window.history.back() on /usage or refreshes its listener after the route changes. Add the history handler to the test harness and assert that the second configured shortcut press returns to the previous route.

Add a caller-level browser regression test for NavigationHistoryShortcuts.

The new browser test covers only CommandPalette and observes routeState.navigate. It does not mount NavigationHistoryShortcuts. A future removal of usagePageOpen from that handler's matcher context or effect dependencies could leave its listener stale after a route change. The resolver tests would still pass because they call resolveShortcutCommand directly with synthetic context.

Add a test that mounts AppSidebarLayout or the app root, transitions to /usage, and asserts that the shortcut calls window.history.back().
