Changes Made

Provide default COGSOL_API_BASE and COGSOL_CONTENT_API_BASE values across the project and update docs/.env examples to use https://apis-imp.cogsol.ai. Code changes add fallbacks for the API and Content API base URLs in core client, agents, content, and management commands (chat, importagent, ingest, migrate, startproject, topics) so the app won't fail when env vars are missing. README and documentation examples were updated accordingly, and typing-extensions was added to pyproject.toml dependencies.

Testing Done

• Tested manually

Great. A couple of suggestions:

• Maybe add a constants.py file that contains the two URLs as constants, and use those constants everywhere instead of hardcoding the URLs directly (since they’re repeated a lot, and it’ll be easier to change them if we ever need to).
• In the file management/commands/startproject.py (line 198), the .env.example for the scaffolding is created with localhost in COGSOL_API_BASE and COGSOL_CONTENT_API_BASE. I’d remove those two directly from the .env.example, since most people will use the default ones anyway (maybe I’d do the same in the documentation: remove them from the example .env files).
