This pull request adds support for managing OBS Studio on Windows using
Winget, including new install and uninstall scripts for automated
deployment and removal. The main changes are the introduction of a
metadata file for OBS Studio and robust PowerShell scripts to handle
silent installation and uninstallation.
**OBS Studio Winget Integration:**
* Added a new metadata file `obs.json` describing OBS Studio for Winget
management, including identifiers, script paths, and default categories.
**Installation Script:**
* Introduced `obs_install.ps1`, a PowerShell script that installs OBS
Studio silently using the `/S` flag, captures the installer exit code,
and handles errors gracefully.
**Uninstallation Script:**
* Added `obs_uninstall.ps1`, a PowerShell script that locates the OBS
Studio uninstaller via the Windows registry, ensures all running OBS
processes are stopped, parses the uninstall command, and performs a
silent uninstall (also with `/S`), including error handling and exit
code reporting.
