What this does

• Introduces .node-version to specify node version

Align this repo with the CLI node version.

The .node-version file is used in Node.js projects to specify the version of Node.js required for the project. It helps developers and automated tools like version managers (e.g., nvm, fnm) to ensure the correct Node.js version is used.

• Upgrades shescape to v2.1.0

The shescape pkg has deprecated all versions lower than v2. This change updates to the new interface. Please validate these changes against the migration document: https://github.com/ericcornelissen/shescape/blob/HEAD/docs/migration.md

In addition support has been dropped for older versions of node.
