## Summary of the Pull Request
This pull request introduces a minor but important update to the
`ContentIcon` control in the `Microsoft.CmdPal.UI` module. The changes
improve robustness by adding checks to prevent duplicate parenting of
the `Content` element and include a debug assertion for better
diagnostics during development.
## PR Checklist

## Detailed Description of the Pull Request / Additional comments
### Key changes:
#### Diagnostics and robustness improvements:
* Added a `Debug.Assert` statement to verify that the `Content` element
is not already parented to another element, helping to catch potential
issues during development.
(`[src/modules/cmdpal/Microsoft.CmdPal.UI/Controls/ContentIcon.csR39-R49](diffhunk://#diff-330aad69f925cf7a9e07bb7147af8e6cd09776a4c745455ac8a91a24b482d076R39-R49)`)
* Introduced checks to ensure the `Content` element is not added to the
`Grid`'s `Children` collection if it already exists there, preventing
redundant operations.
(`[src/modules/cmdpal/Microsoft.CmdPal.UI/Controls/ContentIcon.csR39-R49](diffhunk://#diff-330aad69f925cf7a9e07bb7147af8e6cd09776a4c745455ac8a91a24b482d076R39-R49)`)
#### Code maintenance:
* Added a `using System.Diagnostics` directive to enable the use of the
`Debug` class for assertions.
(`[src/modules/cmdpal/Microsoft.CmdPal.UI/Controls/ContentIcon.csR5](diffhunk://#diff-330aad69f925cf7a9e07bb7147af8e6cd09776a4c745455ac8a91a24b482d076R5)`)
## Validation Steps Performed
Turned extensions off and on and off and on and off and on and off and
on and off and on and off and on and off and on and off and on and off
and on and off and on and off and on and off and on and off and on and
off and on and off and on.
And then off and on again, just to be sure.

Both `TopLevelCommandItemWrapper` and `TopLevelViewModel` were really the same thing. The latter was from an earlier prototype, and the former is a more correct, safer abstraction. We really should have only ever used the former, but alas, we only used it for the SUI, and it piggy-backed off the latter, and that meant the latter's bugs became the former's.
tldr: I made the icon access safe in the SUI.
And while I was doing this, because we now have a cleaner VM abstraction here in the host, we can actually cleanly disable extensions, because the `CommandProviderWrapper` knows which `ViewModel`s it made.

Windows Command Palette ("CmdPal") is the next iteration of PowerToys Run. With extensibility at its core, the Command Palette is your one-stop launcher to start _anything_.
By default, CmdPal is bound to <kbd>Win+Alt+Space</kbd>.


----
This brings the current preview version of CmdPal into the upstream PowerToys repo. There are still lots of bugs to work out, but it's reached the state we're ready to start sharing it with the world. From here, we can further collaborate with the community on the features that are important, and ensuring that we've got a most robust API to enable developers to build whatever extensions they want.
Most of the built-in PT Run modules have already been ported to CmdPal's extension API. Those include:
* Installed apps
* Shell commands
* File search (powered by the indexer)
* Windows Registry search
* Web search
* Windows Terminal Profiles
* Windows Services
* Windows settings
There are a couple new extensions built-in
* You can now search for packages on `winget` and install them right from the palette. This also powers searching for extensions for the palette
* The calculator has an entirely new implementation. This is currently less feature complete than the original PT Run one - we're looking forward to updating it to be more complete for future ingestion in Windows
* "Bookmarks" allow you to save shortcuts to files, folders, and webpages as top-level commands in the palette.
We've got a bunch of other samples too, in this repo and elsewhere
### PowerToys specific notes
CmdPal will eventually graduate out of PowerToys to live as its own application, which is why it's implemented just a little differently than most other modules. Enabling CmdPal will install its `msix` package.
The CI was minorly changed to support CmdPal version numbers independent of PowerToys itself. It doesn't make sense for us to start CmdPal at v0.90, and in the future, we want to be able to rev CmdPal independently of PT itself.

TODOs et al
**Blocking:**
- [ ] Images and descriptions in Settings and OOBE need to be properly defined, as mentioned before
- [ ] Niels is on it
- [x] Doesn't start properly from PowerToys unless the fix PR is merged.
- https://github.com/zadjii-msft/PowerToys/pull/556 merged
- [x] I seem to lose focus a lot when I press on some limits, like between the search bar and the results.
- This is https://github.com/zadjii-msft/PowerToys/issues/427
- [x] Turned off an extension like Calculator and it was still working.
- Need to get rid of that toggle, it doesn't do anything currently
- [x] `ListViewModel.<FetchItems>` crash
- Pretty confident that was fixed in https://github.com/zadjii-msft/PowerToys/pull/553
**Not blocking / improvements:**
- Show the shortcut through settings, as mentioned before, or create a button that would open CmdPalette settings.
- When PowerToys starts, CmdPalette is always shown if enabled. That's weird when just starting PowerToys/ logging in to the computer with PowerToys auto-start activated. I think this should at least be a setting.
- Needing to double press a result for it to do the default action seems quirky. If one is already selected, I think just pressing should be enough for it to do the action.
- This is currently a setting, though we're thinking of changing the setting even more: https://github.com/zadjii-msft/PowerToys/issues/392
- There's no URI extension. Was surprised when typing a URL that it only proposed a web search.
- [x] There's no System commands extension. Was expecting to be able to quickly restart the computer by typing restart but it wasn't there.
- This is in PR https://github.com/zadjii-msft/PowerToys/pull/452
