Create documentation for core API

[TanGentleman]

The contents of server.py will end up being the exposed parts of the core of this project. I may support routing to the Screenpipe SDK currently in screenpipe.py. This would allow an agent to plan a task and execute screenpipe searches, and I want to expose only certain API endpoints to each Agent.

Side note, I really like projects like these:

I want to see how compatible they could be with an integration into our Filter/Pipe endpoints so that they are OWUI friendly too.

Perhaps the agent architecture in #29 with a defined task + next step endpoint could work with both!
