- Remove nested git repository from bugulma/frontend/.git - Add all frontend files to main repository tracking - Convert from separate frontend/backend repos to unified monorepo - Preserve all frontend code and development history as tracked files - Eliminate nested repository complexity for simpler development workflow This creates a proper monorepo structure with frontend and backend coexisting in the same repository for easier development and deployment.
