Features

• Reads version from tauri.conf.json (supports version pointing to a package.json path)
• Supports {version} placeholder in --base-url
• Auto-detects build artifacts from target/release/bundle/ and target/<triple>/release/bundle/
• Reads signature content from .sig files
• Appends to existing latest.json if present (errors on duplicates by default)
• Copies distribution files to output directory
• Generates both basic (os-arch) and extended (os-arch-bundle) platform keys
• Supports macOS universal builds (registers for both x86_64 and aarch64, without overwriting native builds)
