GitHub actions workflow to automate build

[ewels]

Vibe-coded a GitHub actions workflow using Cursor to automatically build the .zip and .dmg release assets. This workflow is triggered under the following conditions:

1. Push to master
2. New PR / new commit to an open PR
3. On demand (once merged, under the Actions tab using the "Run workflow" dropdown menu)
4. When a new release is created

For 1-3, the built assets are available as artefacts on the GitHub actions run itself.

For releases, the assets are added to the release. See https://github.com/ewels/FastQC/releases/tag/v1.234 for an example:

Should all be fully automated, just to make life a little easier.

Warning

I confess I haven't actually checked the built assets much to see if they're functional. I tried with the MacOS DMG but nothing happens when I double click the icon. I get the same behaviour when I try with one of the official releases off the Babraham site though.. 🤷🏻‍♂️
