Asset Share Tool - Cross-Project Asset Sharing

Asset Share is a Unity Editor workbench that mounts external shared asset folders directly under the current project's `Assets` directory. Maintain models, textures, materials, audio, reusable code, and editor tools in one place while making them available to multiple projects. The workbench clearly manages each source path, mount location, and connection status. Unmounting removes only the project entry and never deletes the shared source. Every record can be customized with its own name, source, and mount path, while global settings provide a default mount directory and confirmation for important actions. Shared link lists can be imported and exported as JSON for easy configuration transfer between projects or team members. Asset Share is designed for developers managing multiple Unity projects, common asset libraries, large content folders, or collaborative workflows. The interface supports Simplified Chinese, English, Japanese, and Korean with instant language switching.
