Clean up development planning artifacts reflecting new approach
Problem: following the attempt to use issues and devlog to plan and log what was done, the conclusion was that:
It was cumbersome in many respects, and did not solve the issue of collecting valuable insights to create worthy daily activity logs
I was attempting to automate the creation of something I had never tried to create manually. So I would focus on writing good logs first before automating the process.
Remove AI orchestration issue tracking system (devlog.md, issues.md)
Remove slash commands for issue management (/issue, /close)
