Build out this Python project into a working app called Second Self.

I want the code organized cleanly, with the existing data, docs, lib, static, and wiki folders actually used in a sensible way. Make sure the main Python script works end to end, set up the environment variables from the example file, and include anything needed so someone can install the dependencies and run it without guessing. If there are any missing details, use the current docs or look up the latest info online if you need to.

Please also make it easy to understand what the project does by adding clear docs and a simple way to test that everything is working.
