chore: Update the environment (#64)

This pull request updates project configuration files to modernize
tooling and clarify environment requirements. The main changes include
updating dependencies to newer versions, renaming a script for
consistency, and specifying the required Node.js version and package
manager.

**Tooling and dependency updates:**

* Updated development dependencies in `package.json` to newer versions
for tools such as `jest`, `eslint`, `typescript`, and related plugins.
* Improved the `jest` transform configuration formatting for better
readability.

**Project configuration and environment:**

* Renamed the `lint-fix` script to `lint:fix` in `package.json` for
consistency with common naming conventions.
* Added `engines` field to specify required Node.js version (>=22) and
declared the package manager as `[email protected]` in `package.json`.
* Removed the `.node-version` file, which previously pinned Node.js to
version 22.12.0, in favor of the new `engines` field.
