Toy chatbot

by @alex-moon

I'm vibe coding a toy chatbot with OpenCode and GLM 5.3 - I'll open source it once it's meaningfully done (keeping the repo private for now until I am _so so_ sure there are no secrets in it!). This has been an exercise in learning about lots of new AI SWE concepts including some tech (Mastra, LangSmith, DeepInfra) - as well as a chance to try some open weights models. The actual useful output is an iteration loop orchestrator based on GitHub issues/PRs which I have found a lot of fun to use. That'll also be open-sourced.
