Add a new configuration option `run-after-update` that specifies a program to launch automatically after the update process completes. When set to an empty string (default), no program is launched. When set to a path like "Plain Craft Launcher 2.exe", the specified program is spawned after all updates are applied. This is particularly useful for launching PCL2 or other Minecraft launchers immediately after updating modpack files.

```yaml
Program to launch after update completes
Leave empty to do nothing
Example: "Plain Craft Launcher 2.exe"
run-after-update: ""
```
Testing
Tested on both Debug and Release profiles on Windows.
Notes
The program is spawned via `std::process::Command::new(...).spawn()` after the update workflow returns `Ok(())`. If the program path is invalid, the error is silently ignored to avoid interrupting the update flow. The spawned program runs in the background and does not block the update exit.
