7.66 Remove Babel Packages and Configs

Summary

Perform a final cleanup pass to remove any remaining Babel packages, configuration files, and script references from the backend, confirming the toolchain relies fully on TypeScript and native Node.

Tasks

• Search for Babel-related usage:
  - grep -r "babel" package.json app/ .eslintrc*
  - ls -a for .babelrc, babel.config.*
• Remove any remaining Babel packages from package.json (if present) and reinstall dependencies
• Delete residual Babel config files:
  - .babelrc, babel.config.js or similar
• Update package.json scripts to ensure no babel CLI invocation remains
• Confirm ESLint config uses @typescript-eslint/parser and not babel-eslint
• Run TypeScript compilation and linting
• Commit dependency, script, and config changes

Expected Behavior

The backend build and runtime pipelines operate entirely through TypeScript and Node, with no Babel packages or configuration remaining.

Tech Notes

• This task validates and finalizes work started in earlier Babel-removal issues by sweeping for any residual references.
• Keep a reference to prior Babel-based configuration only in version control history if needed.

Acceptance Criteria

• No Babel-related packages appear in package.json or the lockfile
• No Babel config files exist in the repository
• No babel references remain in project scripts or configs
• TypeScript compile, lint, and test commands complete successfully

Test Instructions

1. Run pnpm install after any dependency changes.
2. Run grep -r "babel" . and confirm only historical references (e.g., in CHANGELOG or docs, if any) remain.
3. Run npx tsc --noEmit and pnpm lint.
4. Run pnpm test and verify all tests pass.
