Try using the new experimental app-sdk and app-sdk-react

[HappyPaul55]

This is a major code change, but from a users point of view, this is minor - if anything, it's smaller bundle sizes and quicker load times.

This pull request introduces a major overhaul of the project, transitioning from a pnpm-based Node.js setup to a deno-based environment. It includes the removal of legacy configurations, updates to workflows, and adjustments to development and build processes. Below is a summary of the most important changes:

Transition to Deno

• Updated .devcontainer/devcontainer.json to replace pnpm with Deno, including the installation of Deno via onCreateCommand and replacing the pnpmVersion field with pnpmVersion. Additionally, the ESLint extension was replaced with the Deno extension. [1] [2]
• Changed .vscode/launch.json and .vscode/tasks.json to replace pnpm commands with equivalent Deno commands for building and testing. [1] [2] [3]

Removal of Legacy Configurations

• Deleted .babelrc.json, .eslintignore, .eslintrc.js, and .npmrc, as these are no longer relevant in the Deno-based environment. [1] [2] [3] [4]
• Removed Jest-related files (cssTransform.js, fileTransform.js, global-setup.js, and custom-jest-resolver.js) from the config/jest directory, as the testing framework has been replaced. [1] [2] [3] [4]

Workflow Updates

• Updated .github/workflows/subworkflow-build.yml to replace pnpm linting, testing, and building commands with Deno equivalents. Additionally, removed Sentry-related environment variables and commands.

Documentation Updates

• Updated README.md, SETUP.md, and DESCRIPTION.md to reflect the transition to Deno and improve formatting for readability. [1] [2] [3] [4] [5] [6]

Miscellaneous

• Updated LICENSE.md to reflect the copyright year change from 2024 to 2025.

This transition simplifies the development environment and aligns the project with modern tooling, while removing outdated dependencies and configurations.
