## Summary of the Pull Request
- Adds a new **"Restart Windows Explorer"** command to the **"Windows
System Commands"** provider
- Implemented using **Restart Manager** to allow restoring previously
opened Explorer windows after restart
- This depends on the *"Restore previous folder windows at logon"*
option in File Explorer Options
- An explicit timeout was added for terminating processes, since Restart
Manager uses very long timeouts 😴
- The shell process name (`explorer`) is hardcoded
- The command attempts to terminate all `explorer` processes
indiscriminately
- Execution requires confirmation (if enabled in settings)

## Validation Steps Performed
On a reload, the system commands fallback would leave the "restart"
fallback behind, for the same reason as what we found around
e40372c & ef264d9 in #38455
**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
