Introduced monorepo and packagesPublic

The user just said "hi yeah, this is nice" which is a casual greeting without a concrete task. According to the AGENTS.md, if the user did not give a concrete task in their first message, I should read README.md and then ask which module(s) to work on.

Good, I've read the README. Now I should ask the user which module(s) they want to work on since they didn't give a concrete task.
