## Summary
This PR refactors CmdPal settings/state to be immutable end-to-end.
### Core changes
- Convert model types to immutable records / init-only properties:
- `SettingsModel`
- `AppStateModel`
- `ProviderSettings`
- `DockSettings`
- `RecentCommandsManager`
- supporting settings types (fallback/hotkey/alias/top-level
hotkey/history items, etc.)
- Replace mutable collections with immutable equivalents where
appropriate:
- `ImmutableDictionary<,>`
- `ImmutableList<>`
- Move mutation flow to atomic service updates:
- `ISettingsService.UpdateSettings(Func<SettingsModel, SettingsModel>)`
- `IAppStateService.UpdateState(Func<AppStateModel, AppStateModel>)`
- Update ViewModels/managers/services to use copy-on-write (`with`)
patterns instead of in-place
mutation.
- Update serialization context + tests for immutable model graph
compatibility.
## Why
Issue #46437 is caused by mutable shared state being updated from
different execution paths/threads,
leading to race-prone behavior during persistence/serialization.
By making settings/app state immutable and using atomic swap/update
patterns, we remove in-place
mutation and eliminate this class of concurrency bug.
## Validation
- Built successfully:
- `Microsoft.CmdPal.UI.ViewModels`
- `Microsoft.CmdPal.UI`
- `Microsoft.CmdPal.UI.ViewModels.UnitTests`
- Updated unit tests for immutable update patterns.
Fixes#46437

In #41959 we changed the string matcher's weighting. It ended up giving
us lower scores than before.
That meant that the weighting from recent commands was far too heavy,
and it was polluting the results. Basically any command that you'd run
would be like, 30 characters of weight heavier than anything you
haven't.
This increases the weight of all string matches by 10x. That means
something like
`Command Prompt` will get a string matched weight of `100` instead of
`10`. This balances better with the weighting from frecency (where the
MRU command gets +35, then `+min(5*uses,35)`, for up to 70 points of
weight)
It also adds a bunch of tests here, to try and catch this again in the
future.
Closes#42158
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
};
```
According to Issue #40447 Without the Lock in RecentCommandsManager we
get Exception:
Collection was modified; enumeration operation may not execute.
It indicated that while GetCommandHistoryWeight was enumerating History,
another method (likely AddHistoryItem) modified it at the same time.
Since List is not thread-safe, simultaneous read+write can break it.

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.
Closes#3200, closes#3600, closes#7770, closes#34273, closes#36471, closes#20976, closes#14495

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
