Piping ( | ) to ai

Hi there, I really like your project :)
It is the one i use most often along side [yai](https://github.com/ekkinox/yai/) which i also like

Wanted to request a feature to **allow data piping in and out of the ai**
please draw inspiration from [openai_pipe](https://github.com/Aesthetikx/openai_pipe) 👈
there are really good examples showcased in the main Readme

Also, i think your best feature is the **Revise** option, but sadly, if i do a couple of revisions, i cant continue the conversation, and say stuff like "the previous version was better, but remember to...". pleassse add context of atleast the current run of revision (not even mentionion context from previous sessions)
Thanks a lot and all the best!

Start by reviewing the CLI's current Revise flow and the piping examples in the linked openai_pipe README. Define how data should enter and leave the CLI and how revision context should persist, then verify both requested behaviors with representative command-line usage.
