## Summary of the Pull Request
This change marks the System command provider as special, ensuring
fallback items are surfaced at the top of the list.
Additionally, the SystemCommandExtensionProvider ID has been updated to
comply with the new naming convention.
As a small cleanup, SystemCommandExtensionProvider is now sealed.

<!-- Describe how you validated the behavior. Add automated tests

## Validation Steps Performed
Ran locally, looks good.
Still a WIP, but here's the deets so far:
## No more throwing canceled tokens
Throwing exceptions is expensive and since we essentially cancel tokens
anytime someone is typing beyond the debounce, we could be throwing
exceptions a ton during search. Since we don't care about those past
executions, now they just `return`.
## Reduced number of apps returned in search
While users can specify how many apps (no limit, 1, 5), if they specify
no limit, we hard limit it at 10. For a few reasons, fuzzy search gets
_really_ fuzzy sometimes and gives answers that users would think is
just plain wrong and they make the response list longer than it needs to
be.
## Fuzzy search: still fuzzy, but faster
Replaced `StringMatcher` class with `FuzzyStringMatcher`.
`FuzzyStringMatcher` is a C# port by @zadjii-msft of the Rust port by
@lhecker for [microsoft/edit](https://github.com/microsoft/edit), which
I believe originally came from [VS
Code](https://github.com/microsoft/vscode). It's a whole fuzzy rabbit
hole. But it's faster than the `StringMatcher` class it replaced.
## Fallbacks, you need to fall back
"In the beginning, fallbacks were created. This had made many people
very angry and has been widely regarded as a bad move."
Hitchhiker's Guide to the Galaxy jokes aside, fallbacks are one cause of
slower search results. A few modifications have been made to get them
out of the way without reverting their ability to do things dynamically.
1. Fallbacks are no longer scored and will always* appear at the bottom
of the search results
2. In updating their search text, we now use a cancellation token to
stop processing previous searches when a new keypress is recorded.
## * But Calculator & Run are special
So, remember when I said that all fallbacks will not be ranked and
always display at the bottom of the results? Surprise, some will be
ranked and displayed based on that score. Specifically, Calculator and
Run are fallbacks that are whitelisted from the restrictions mentioned
above. They will continue to act as they do today.
We do have the ability to add future fallbacks to that whitelist as
well.

## Summary of the Pull Request
This PR ensures that fallback items consistently display an icon in
Settings window:
- Adds a new `InitialIcon` property to `TopLevelViewModel` to store the
first non-empty icon received.
- Uses `InitialIcon` in the extension settings page when listing
fallback items belonging to an extension.
- Sets initial icons in the constructor for fallback items that were not
previously initialized:
- Date & Time extension
- System Commands extension
- The Windows Settings extension had its icon initially set, but it was
cleared when the item was updated for an empty search query. By
persisting the initial icon, subsequent updates no longer affect how the
fallback item is represented in Settings.
This change is considered a hotfix for the current state.
The ideal long-term solution would be to declare the `DisplayIcon` on
fallback item explicitly, similar to `DisplayTitle`.

## Detailed Description of the Pull Request / Additional comments
<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
- Verified that icons are correctly displayed for all built-in
extensions.
- Confirmed correct behavior with third-party extensions (e.g., Colors
for Command Palette).
- Tested in Release configuration with AOT enabled.
It would seem that the way we absorb the icons for built-in extension
into our package relies on the _extension_ package including WASDK. I
don't fully understand why.
This PR adds a common `.props` file we can use for all extensions, to
make sure they include it.
regressed in #41261Closes#41279
What the title says. 😄
Rather than relying on the potentially overloaded `!=` or `==` operators
when checking for null, now we'll use the `is` expression (possibly
combined with the `not` operator) to ensure correct checking. Probably
overkill for many of these classes, but decided to err on the side of
consistency. Would matter more on classes that may be inherited or
extended.
Using `is` and `is not` will provide us a guarantee that no
user-overloaded equality operators (`==`/`!=`) is invoked when a
`expression is null` is evaluated.
In code form, changed all instances of:
```c#
something != null
something == null
```
to:
```c#
something is not null
something is null
```
The one exception was checking null on a `KeyChord`. `KeyChord` is a
struct which is never null so VS will raise an error when trying this
versus just providing a warning when using `keyChord != null`. In
reality, we shouldn't do this check because it can't ever be null. In
the case of a `KeyChord` it **would** be a `KeyChord` equivalent to:
```c#
KeyChord keyChord = new ()
{
Modifiers = 0,
Vkey = 0,
ScanCode = 0
};
```

## Summary of the Pull Request
Ok... The AI generated and migrated ut's quality is very poor. We need
to refactor it.

Just standardizing built-in extensions to use a `internal sealed class
Icons` for all their non-dynamic icons.
Looks like a LOT of changes, but it's icons all the way down.

## Summary of the Pull Request
- Adds a new **"Restart Windows Explorer"** command to the **"Windows
System Commands"** provider
- Implemented using **Restart Manager** to allow restoring previously
opened Explorer windows after restart
- This depends on the *"Restore previous folder windows at logon"*
option in File Explorer Options
- An explicit timeout was added for terminating processes, since Restart
Manager uses very long timeouts 😴
- The shell process name (`explorer`) is hardcoded
- The command attempts to terminate all `explorer` processes
indiscriminately
- Execution requires confirmation (if enabled in settings)

## Summary of the Pull Request
Base on my test, some built-in extensions can be published with native
AOT enabled with a little changes. (see this branch:
https://github.com/microsoft/PowerToys/pull/39605).
1. SystemCommands: no change need. Removed some unused code.
2. WinGet: disable marshalling. and do a little changes in
CreateInstance.
3. WindowWalker: use source generation to call CoCreateInstance.
4. WindowsTerminal: use source generation to call
IApplicationActivationManager interface.

On a reload, the system commands fallback would leave the "restart"
fallback behind, for the same reason as what we found around
e40372c & ef264d9 in #38455
**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
