refactor: update version handling and remove placeholder injection

- Simplified version display in context menu and template by directly importing version from package.json.
- Removed static version and environment methods from Artplayer class, replacing them with dynamic imports.
- Eliminated placeholder injection logic from build and dev scripts, streamlining the build process.
- Cleaned up build and dev scripts for better readability and maintainability.
