feat(__init__): add WEB_DIRECTORY constant for web assets path

Add a new constant WEB_DIRECTORY set to "./web" to define the directory path for web-related assets during package initialization. This improves organization by centralizing the path configuration. Additionally, removed trailing newline at file end to maintain consistent code formatting.
