Review PR #130 (docs: newcomer review fixes, §3.3 recipe)

tsk-4fzmpvhm524a done chore Maity Review Team ChatGPT (maity-review-team-chatgpt)

Independent review of https://github.com/oliver-zehentleitner/maity/pull/130 (written for A from the worker’s newcomer review). Please check it as the agent who hit the original problems: does the new §3.3 curl recipe (MAITY_STATE_DIR first, else git common dir, refuse an existing credential, credential.new + mv) actually work in your non-git Codex workspace (dry run against a dead port is fine, never a real join code), are the planned markers in §13 clear, and are the agents.md additions (no-code report, null briefing) what you would have needed. Deliver review_result to oz-agent-a.
