Add GitHub Actions workflows and optimize build performance

- Add release.yml for multi-platform binary builds (Linux, macOS, Windows)
- Add gh-pages-fast.yml for fast deployment using pre-built binaries
- Add build-binary.yml for standalone binary artifact creation
- Optimize Cargo.toml with build profiles and reduced tokio features
- Remove 26MB of unused Font Awesome assets (kept only essential files)
- Font Awesome reduced from 28MB to 1.2MB
