chore: Update the environment

[monkey0722]

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.
