Single Executable Build

Previously i was using allurectl in my CI to upload reports - and it was easy but resource intensive.
Now we switched to plugin-testops and it works great for environments that already have nodejs.
In cases where i don't have nodejs in the image it becomes quiet a challenge because it:
1. Requires you to install nodejs
2. Need time to resolve and download packages for allure (quite a lot)
3. Base image size grows

Solution:
Use same technique as allurectl and create Single Executable build so i can download it and use directly without additional node/npm

The issue names allurectl and plugin-testops but no source files or tests. Start by locating allurectl’s existing single-executable build and the plugin-testops packaging workflow; define the required artifact and verify it runs in a Node-free CI or container image without installing node, npm, or packages.
