Add official-Auralin local AI research update agent

[official-Auralin]

Summary

Submit studio/official-Auralin/ with the local research update agent, delegation card, student-authored explanation, and reviewed verification artifacts. All changes are confined to this team folder.

• Monitor Anthropic News, Anthropic Engineering, and OpenAI News, with deduplication and evidence-validated summaries.
• Write dated daily Markdown reports; keep coverage warnings in separate logs and exclude private runtime files from Git.
• Document the local weekday 9:00 AM America/New_York schedule and operating instructions.
• Preserve the student's explanation unchanged.

Verification

• python3 -m unittest discover -s code/tests -v from studio/official-Auralin: 21 tests passed.
• Included reviewed live-run evidence covering summaries, OpenAI RSS fallback after article access failures, and an unchanged repeat run.
• Live state, raw pages, and personal runtime traces are ignored; only reviewed verification artifacts are committed.

The local scheduler configuration is machine-specific and is documented rather than committed. The scheduled trigger itself has not yet been observed firing.
