- Added comprehensive comments and JSDoc-style documentation to NotificationProvider, ThemeProvider, UserProvider, and WebsiteThemeProvider for better clarity and maintainability.
- Improved type definitions in index.ts for better code understanding and usage.
- Introduced Docker support with Dockerfiles for various services including AI server, signaling server, and browser-use service.
- Created a docker-compose.yml file to orchestrate multiple services including PostgreSQL, AI, scraper, and frontend.
- Added a startup guide (startup.txt) for setting up the CRM environment on Ubuntu with Docker.
- Included a .dockerignore file to exclude unnecessary files from Docker builds.
