📦 CI/CD & Releases

This project uses GitHub Actions for automated cross-platform builds.

• Trigger: Pushing a tag (e.g., v1.0.0) triggers the workflow.
• Platforms: Builds specifically for Windows (.exe), macOS (.app), and Linux.
• Releases: Automatically creates a GitHub Release and uploads zipped assets.

macOS Note

If you download the .app directly, you might see a "damaged" or "unverified" warning. This is standard macOS Gatekeeper behavior for unsigned apps. Fix: Run xattr -cr /path/to/web-seo.app in your terminal to allow it to run.
