feat: Improve developer experience and codebase quality

This commit introduces a series of improvements to the project to enhance the developer experience and overall codebase quality.

- **Dependency Management:**
  - Updated all dependencies to their latest stable versions.
  - Replaced the alpha version of `@google/clasp` with a stable release.
  - Added `jest` for testing and `eslint-plugin-jsonc` for linting JSON files.

- **Scripts:**
  - Added `lint`, `format`, and `test` scripts to `package.json`.
  - The `test` script is configured to run with Node's experimental VM modules to support ES modules.

- **ESLint Configuration:**
  - Removed redundant ESLint rules to avoid conflicts.
  - Configured ESLint to lint JSON files, ensuring consistency.
  - Added a `.eslintignore` file to exclude generated files from linting.

- **Prettier Configuration:**
  - Created a `.prettierrc` file to centralize formatting rules.
  - Added a `.prettierignore` file to exclude generated files from formatting.

- **Testing:**
  - Added a basic test case for a utility function.
  - Refactored a function to make it testable and independent of the Google Apps Script API.
