Some checks failed
farmcontrol/farmcontrol-server/pipeline/head There was a failure building this commit
- Introduced a new script for preparing application icons, supporting macOS, Windows, and Linux formats. - Updated electrobun.config.ts to specify paths for app icons in the build configuration. - Added generated app icons to .gitignore to prevent tracking of build artifacts. - Updated package.json and bun.lock to include the png-to-ico dependency for icon conversion.
