Draft CONTRIBUTING.md and CODE_OF_CONDUCT.md

• Actions Taken:
  • Created the first drafts of the CONTRIBUTING.md and CODE_OF_CONDUCT.md files. The CONTRIBUTING.md was heavily revised to reflect the Matrix-centric, AI-agent-mediated workflow.
• Friction/Success Points:
  • A significant oversight was the failure to immediately log this activity in the DEVLOG.md, highlighting a need for stricter adherence to logging conventions.
