Merge branch 'main' of https://github.com/microsoft/PowerToys into leilzh/replacecal

This pull request introduces a new unit testing framework for the
`WorkspacesLib` module, adds test coverage for various utilities, and
integrates the new test project into the build system. Key changes
include adding the `WorkspacesLibUnitTests` project, implementing tests
for `AppUtils`, `JsonUtils`, and `PwaHelper`, and updating the build
configuration to include the new test project.

### Unit Tests Added:
* **`AppUtilsTests`**:
- Added comprehensive tests for methods such as `GetCurrentFolder`,
`IsEdge`, `IsChrome`, and `IsSteamGame` to validate their behavior under
various conditions.
* **`JsonUtilsTests`**:
- Implemented tests for reading and writing workspace data, including
scenarios for invalid JSON, non-existent files, and valid workspace
lists.
* **`PwaHelperTests`**:
- Added tests to ensure the stability of `PwaHelper` methods, such as
`GetEdgeAppId`, `GetChromeAppId`, and `SearchPwaName`, even with invalid
or empty inputs.

### Build System Updates:
* **New Test Project Integration**:
- Added the `WorkspacesLibUnitTests` project to the solution file
`PowerToys.sln` with appropriate dependencies.
- Updated build configurations to include the new test project for both
Debug and Release builds across architectures.

### Pipeline Adjustments:
* **Test Discovery**:
- Updated the pipeline configuration in
`.pipelines/v2/templates/job-build-project.yml` to discover the new
`WorkspacesLibUnitTests.dll` during test runs.

+# C++/WinRT CalculatorEngine Project Overview
+
+This project wraps the exprtk expression parsing library with a C++/WinRT component,  
+making advanced mathematical evaluation capabilities available to Windows applications.  
+It is designed specifically to provide calculation support for the CmdPal calculator extension.
+
+## Using exprtk
+
+This project uses [exprtk](https://github.com/ArashPartow/exprtk) as the 
+expression parsing and evaluation engine.
+
+How to use exprtk in this project:
+- The exprtk header file (`exprtk.hpp`) is included in the project source.
+- You can use exprtk to parse and evaluate mathematical expressions in your 
+  C++ code. For example:
+
+    ```cpp
+    #include "exprtk.hpp"
+    exprtk::expression<double> expression;
+    exprtk::parser<double> parser;
+    std::string formula = "3 + 4 * 2";
+    parser.compile(formula, expression);
+    double result = expression.value();
+    ```
+
+How to update exprtk:
+1. Download the latest `exprtk.hpp` from the [official repository](https://github.com/ArashPartow/exprtk).
+2. Replace the existing `exprtk.hpp` file in the project with the new version.
+3. Rebuild the project to ensure compatibility and take advantage of any updates.
