Restore Babel packages required for transpilation

Added back all Babel packages that were removed during SWC migration:
- @babel/cli, @babel/core for core Babel functionality
- @babel/plugin-transform-runtime and presets for transpilation
- babel-loader, babel-plugin-macros, babel-jest for webpack and testing
- Updated Jest to use babel-jest instead of @swc/jest

This restores full Babel functionality for beta.11 with Babel transpiler.
