feat: Create vtk-wasm JavaScript project

- Updated package.json to define project metadata and dependencies.
- Added remote.js for managing remote sessions and state handling.
- Introduced standalone.js for creating VTK objects and handling properties.
- Created viewer.js for loading and displaying VTK data.
- Added wasmLoader.js for loading and managing the VTK WASM library.
- Configured Vite build setups for different output formats (ESM and UMD).

 # vtk-wasm
 
-Guides and documentation for VTK.wasm
+## Project Structure and Build Scripts
+
+This repository provides the infrastructure to bundle the pure JavaScript library for loading VTK.wasm.
+
+### File Structure
+
+- `src/` — Source code for the library.
+- `dist/` — Bundled output files.
+- `wasm/` — WebAssembly binaries and related assets.
+- `scripts/` — Utility scripts for building and packaging.
+- `README.md` — Project documentation.
+- `package.json` — Project metadata and build scripts.
+
+### Build Scripts
+
+The following scripts are available in `package.json`:
+
+- **`npm run docs:build`** - Builds the guide pages for VTK.wasm
+- **`npm run build`** — Builds the ESM and UMD bundles for both RemoteSession and StandaloneSession.
+- **`npm run build:esm`** — Builds only the ESM bundles.
+- **`npm run build:vtk`** — Builds only the UMD bundle for StandaloneSession.
+- **`npm run build:viewer`** - Builds the vtkWASMViewer JavaScript library.
+- **`npm run clean`** — Cleans the `dist/` directory.
+- **`npm run lint`** — Runs code linting on the source files.
+
+### Bundles
+
+- **ESM Bundles:** For both RemoteSession and StandaloneSession.
+- **UMD Bundle:** For StandaloneSession, exposed as the `VTK` namespace for use in browser environments.
+
+Refer to the `package.json` for the full list of scripts and configuration details.
