The Docker browser build fails because yarn cannot install `@electron/node-gyp` from GitHub without git. ## Changes - Add git to builder stage in `Dockerfile.browser` - Git is excluded from final production image via multi-stage build ## Technical Details The `yarn.lock` contains a git-based dependency: ``` "@electron/node-gyp@https://github.com/electron/node-gyp#06b29aafb7708acef8b3669835c8a7857ebc92d2" ``` Alpine Linux base image lacks git by default. Installing it only in the builder stage (where `yarn install` runs) resolves the build failure without affecting production image size. <!-- START COPILOT CODING AGENT SUFFIX --> <!-- START COPILOT ORIGINAL PROMPT --> <details> <summary>Original prompt</summary> > fix https://github.com/thomasnordquist/MQTT-Explorer/actions/runs/20442696351/job/58739200179 </details> <!-- START COPILOT CODING AGENT TIPS --> --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.
