## Summary of the Pull Request
This PR updates the PowerToys solution to support **Visual Studio 2026
(PlatformToolset v145)**. It centralizes the build configuration,
updates the C++ language standards, and fixes an issue with a MouseJump
unit test that appears while using the VS 2026 supported build agent.

## Detailed Description of the Pull Request / Additional comments
**Build System & Configuration:**
- Updated `Cpp.Build.props` to use `v145` (VS 2026) as the default
`PlatformToolset`, with fall back to `v143` for VS 2022.
- Configured C++ Language Standard:
- `stdcpplatest` for production projects.
- Removed explicit `<PlatformToolset>` definitions from individual
project files (approx. 37 modules) to inherit correctly from the central
`Cpp.Build.props`.
**Code Refactoring & Fixes:**
- Updated `DrawingHelperTests.cs` in MouseJump Unit Test to ease the
pixel difference tolerance. This became an issue after switching to the
new VS2026 build agent.
<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
- Validated successful compilation of the entire solution. Similar
updates have been made to the .NET 10 branch, but these are much cleaner
and will be merged into that branch once fully confirmed working.

## Summary of the Pull Request
## Root Cause
WiX-based registration creates persistent Shell Extension entries that:
1. Load DLLs even when the module is disabled
2. Cause cross-OS version conflicts (Win11 loading Win10 extensions)
## Changes Made
1. Removed static Shell Extension registration from PowerToys installer
2. Modified modules to register Shell Extensions during Runner startup
### Modified Modules:
- **PowerRename** (`src/modules/powerrename/dll/dllmain.cpp`)
- **NewPlus**
(`src/modules/NewPlus/NewShellExtensionContextMenu/powertoys_module.cpp`)
- **ImageResizer** (`src/modules/imageresizer/dll/dllmain.cpp`)
- **FileLocksmith**
(`src/modules/FileLocksmith/FileLocksmithExt/PowerToysModule.cpp`)
## Known Migration Issue
**Machine-level installer registry residue**: win10 with machine-level
installers may have residual Shell Extension registry entries that
persist with this change.

## AI Summary
This pull request refactors how shell extension registry keys are
managed during installation and uninstallation for several PowerToys
modules. The main change is moving registry key cleanup logic for
context menu shell extensions (ImageResizer, FileLocksmith, PowerRename,
NewPlus) from static installer definitions to new custom uninstall
actions, ensuring more reliable removal and future extensibility.
**Installer and Uninstall Refactoring**
* Added new custom actions (`CleanImageResizerRuntimeRegistryCA`,
`CleanFileLocksmithRuntimeRegistryCA`,
`CleanPowerRenameRuntimeRegistryCA`, `CleanNewPlusRuntimeRegistryCA`) to
programmatically clean up registry keys for each shell extension during
uninstall, implemented in `CustomAction.cpp` and exported in
`CustomAction.def`.

* Registered these custom actions in `Product.wxs` and ensured they run
before file removal during uninstall.

**Removal of Static Registry Key Definitions**
* Removed static registry key and component definitions for context menu
shell extensions from their respective installer `.wxs` files
(`FileLocksmith.wxs`, `ImageResizer.wxs`, `PowerRename.wxs`,
`NewPlus.wxs`), relying on custom actions for cleanup instead.

**Project File Update**
* Added `shell_ext_registration.h` to the solution file, possibly for
future shell extension registration logic.
These changes improve uninstall reliability and centralize registry
cleanup logic, making future maintenance and extension of shell
extension registration much simpler.
