## Summary of the Pull Request
This pull request introduces enhancements to UI test automation,
improvements to pipeline configuration, and project structure updates.
The goal is to improve flexibility, maintainability, and efficiency in
PowerToys’ CI/CD processes.

### UI Test Enhancements:
Delayed Text Input Support
- UI tests now support character-by-character text input with
configurable delays.
- This serves as a workaround for a known CmdPal bug where input is
swallowed too quickly. The delay mitigates the issue until it is fixed
in CmdPal.
 
Centralized Environment Management
- Introduced a new class to centralize environment variable access for
UI test configuration.

CmdPal Launch Handling in Pipelines

- Adjusted test logic to handle CmdPal module startup specifically in CI
pipelines



### Pipeline Configuration Updates:
Build Artifact Customization

- Included test-related folders in pipeline build outputs for better
traceability.

Support for Build ID Targeting

- Added support for specifying PowerToys build IDs in test pipelines,
with conditional logic for specific or latest build selection.

 ### Building PowerToys Locally
 
+#### One stop script for building installer
+1. Open developer powershell for vs 2022
+2. Run tools\build\build-installer.ps1
+> For the first-time setup, please run the installer as an administrator. This ensures that the Wix tool can move wix.target to the desired location and trust the certificate used to sign the MSIX packages.
+
+The following manual steps will not install the MSIX apps (such as Command Palette) on your local installer.
+
 #### Prerequisites for building the MSI installer
 
 1. Install the [WiX Toolset Visual Studio 2022 Extension](https://marketplace.visualstudio.com/items?itemName=WixToolset.WixToolsetVisualStudio2022Extension).

+## If for any reason, you'd like to test winget install scenario, you can follow this doc:
+
+### Powertoys winget manifest definition:
+[winget repository](https://github.com/microsoft/winget-pkgs/tree/master/manifests/m/Microsoft/PowerToys)
+
+### How to test a winget installation locally:
+1. Get artifacts from release CI pipeline  Pipelines - Runs for PowerToys Signed YAML Release Build, or you can build one yourself by execute the 
+ 'tools\build\build-installer.ps1' script
+
+2. Get the artifact hash, this is required to define winget manifest
+```powershell
+cd /path/to/your/directory/contains/installer
+Get-FileHash -Path ".\<Installer-name>.exe" -Algorithm SHA256
+```
+ 3.  Host your installer.exe - Attention: staged github release artifacts or artifacts in release pipeline is not OK in this step
+You can self-host it or you can upload to a publicly available endpoint  
+**How to selfhost it** (A extremely simple way):
+```powershell
+python -m http.server 8000
+```
+
+4. Download a version folder from wingetpkgs like: [version 0.92.1](https://github.com/microsoft/winget-pkgs/tree/master/manifests/m/Microsoft/PowerToys/0.92.1)
+and you get **a folder contains 3 yml files**
+>note: Do not put any files other than these three in this folder
+
+5. Modify the yml files based on your version and the self hosted artifact link, and modify the sha256 hash for the installer you'd like to use
+
+6. Start winget install:
+```powershell
+#execute as admin
+winget settings --enable LocalManifestFiles
+winget install --manifest "<folder_path_of_manifest_files>" --architecture x64 --scope user
+```
