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.

Closes#39763Closes#39239Closes#39948Closes#38594Closes#40330
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
Adds a new setting that lets users swap Save/Copy as primary/secondary
commands. This is done in order to enable closing on enter (similar to
PTRun) and therefore saving three extra steps (see issue). Defaults to
true - Copy is primary.

This entirely rewrites the shell page. It feels a lot more like the old
run dialog now.
* It's got icons for files & exes
* it can handle network paths
* it can handle `commands /with args...`
* it'll suggest files in that path as you type
* it handles `%environmentVariables%`
* it handles `"Paths with\spaces in them"`
* it shows you the path as a suggestion, in the text box, as you move
the selection

### Remaining todo's
* [x] Remove the `GenerateAppxManifest` change, and file something to
fix that. We are still generating msix's on every build, wtf
* [x] Clean-up code
* [x] Double-check loc
* [x] Remove a bunch of debug printing that we don't need anymore
* [ ] File a separate PR for moving the file (indexer) commands into a
common project, and re-use those here
* [x] Add history support again! I totally tore that out
* did that in #40427
* [x] make `shell:` paths and weird URI's just work. Good test is
`x-cmdpal://settings`
### further optimizations that probably aren't blocking
* [x] Our fast up-to-date is clearly broken, but I think that's been
broken since early 0.91
* [x] If the exe doesn't change, we don't need to create a new ListItem
for it. We can just re-use the current one, and just change the args
* [ ] if the directory hasn't changed, but we typed more chars (e.g.
`c:\windows\s` -> `c:\windows\sys`), we should cache the ListItem's from
the first query, and re-use them if possible.
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
Fixes space handling for CmdPal's Calculator. Windows uses the no-break
space instead of the normal one for locales which use a space for number
group separation, however most users don't realize this and expect
CmdPal to also handle normal spaces as such, hence this PR.

## Detailed Description of the Pull Request / Additional comments
## Validation Steps Performed
Manually tested calculations with spaces as group separators. Doesn't
break with lone standing spaces (e.g. `7 + pi + pi + 7`).
## Summary of the Pull Request
The ExprTk result was previously parsed with CurrentCulture, which means
that calculator was broken on every device which's culture info differed
from what ExprTk returns.
It would probably be better to just obtain the result as a double
directly, but that can wait.

## Detailed Description of the Pull Request / Additional comments
ExprTk, the math library that CmdPal's Calculator uses, returns the
result as a string formatted in `en-US`, therefore we need to also parse
it as `en-US`.
## Validation Steps Performed
Small and large numbers work correctly with all decimal separators
<!-- Enter a brief description/summary of your PR here. What does it

## Summary of the Pull Request
This PR addresses an issue where direct double output from exprtk
evaluation led to precision artifacts (e.g., 12.2 + 10 resulting in
22.199999999999999). This behavior is due to how double represents
decimal fractions in binary.
- To improve user-facing precision, the result is now:
- Converted to decimal for higher decimal accuracy.
- Rounded to fit within 15 total significant digits (integer +
fraction).
- Formatted using "G29" to eliminate unnecessary trailing zeros.
- Cleaned up to remove dangling decimal points.
This ensures more intuitive and readable output like:
- 1.9999999999 → "1.9999999999"
- 100000.9999999999 → "100001"
- 100000.999999999 → "100000.999999999"
This change improves clarity, especially for users entering expressions
expecting decimal-accurate results.

## Summary of the Pull Request
This PR replaces the original Mages-based expression evaluation engine
with a WinRT-wrapped version of Exprtk in the CmdPalCalculator module.
### Key Changes
**Expression Engine:**
- All expression parsing and evaluation now use Exprtk (via a WinRT
wrapper) instead of Mages.
**Base Conversion Handling:**
- Since Exprtk does not support non-decimal (binary, octal, hexadecimal)
input natively, added logic to convert all such inputs to decimal before
evaluation.
**Code Structure:**
- The overall logic and API surface remain unchanged except for the
engine and base conversion handling.
- All previous Mages references and dependencies have been removed.

**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
