Committing this sample for posterity's sake.
This is the product of an experiment: "can an extension know when it's
page was opened / closed?"
And without changing the actual SDK, this **is** possible. It relies on
the fact that CmdPal (the host) needs to register for the `ItemsChanged`
event on list pages, and it does that when the page is loaded, and it
unregisters itself when the page is closed.
This does require manually implementing `IListPage` - you can't just
`override` the `event` in the base class ([that's
illegal](https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca1070)),
and using `new` to shadow it doesn't work either (probably for cswinrt
reasons).
This is the best I came up with.
Refactored ContextMenu into it's own control to allow displaying in
CommandBar and in response to right click on list items.
- Adds "critical" styling to context menu items flagged as `IsCritical`.
This will use the theme to style with correct color.
- Added `SeparatorContextItem` and modified `MoreCommands` to allow for
both `CommandContextItem`s and `SeparatorContextItem`s.
- Right clicking a list item with a context menu will open the context
menu at the position of the click and position the filter box at the top
of the context menu.

## Summary of the Pull Request
This PR updates all application manifest files across the PowerToys
codebase to use **PerMonitorV2** DPI awareness, ensuring optimal
high-DPI display support on modern Windows systems.
## Changes Made
Updated **12 manifest files** to include proper PerMonitorV2 DPI
awareness:
### Files with New DPI Support Added:
- `src/runner/PowerToys.exe.manifest` - Added complete DPI awareness
section
- `src/modules/awake/Awake/app.manifest` - Upgraded from basic
`dpiAware` to PerMonitorV2
### Files Upgraded from PerMonitor to PerMonitorV2:
- `src/modules/colorPicker/ColorPickerUI/App.manifest`
- `src/modules/MouseWithoutBorders/App/MouseWithoutBorders.exe.manifest`
### Files Enhanced for Consistency:
- `src/modules/ShortcutGuide/ShortcutGuide/ShortcutGuide.exe.manifest`
- `src/modules/ZoomIt/ZoomIt/Zoomit.exe.manifest`
- All 5 cmdpal extension manifests
## Technical Implementation
All manifests now use the standardized format that provides:
1. **PerMonitorV2** as the primary DPI awareness mode for Windows 10
Anniversary Update and later
3. **`true/PM`** for backward compatibility with pre-Windows 10 systems
```xml
<application xmlns="urn:schemas-microsoft-com:asm.v3">
<windowsSettings>
<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/PM</dpiAware>
<dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2, PerMonitor</dpiAwareness>
</windowsSettings>
</application>
```

_targets #38573_
At first I just wanted to add support for nested context menus.
But then I also had to add a search box, so the focus wouldn't get weird.
End result:

This gets rid of the need to have the search box and the command bar both track item keybindings - now it's just in the command bar.
Closes#38299Closes#38442
* [x] Re-adds the context menu shortcut text
* [x] Hooks up the keybindings to the search box so that you can just press the keys while you have an item selected, and do a context command
* [x] Hook these keybindings up to the context flyout itself
* [x] Adds a sample for testing
Solves #38271
**WARNING:** This PR will probably blow up all in-flight PRs
at some point in the early days of CmdPal, two of us created seperate
`Exts` and `exts` dirs. Depending on what the casing was on the branch
that you checked one of those out from, it'd get stuck like that on your
PC forever.
Windows didn't care, so we never noticed.
But GitHub does care, and now browsing the source on GitHub is basically
impossible.
Closes#38081
