PR Overview

This pull request refactors the code by deprecating the transform option "isolatedModules" in favor of using TypeScript’s native isolatedModules support. In addition, it updates various Jest configuration files to reference new tsconfig filenames and replaces the legacy commitlint.config.js file with a TypeScript version.

• Removed "isolatedModules" options from Jest transformer configurations
• Updated tsconfig file paths to use the new "-transpiler" variants
• Replaced commitlint.config.js with commitlint.config.ts for improved type safety
