Reference gdoc pipeline

When Justin asks to put something in a Google Doc, use the markdown pipeline at scripts/gdoc/:

• scripts/gdoc/to-drive.sh "Title" input.md — converts markdown to styled .docx and drops it in Google Drive
• scripts/gdoc/reference.docx — style template (Arial, Justin's preferred formatting)
• Google Drive is live-mounted at /mnt/workspace/Google-Drive/
• Naming convention: YYYY-MM-DD_Title-Case-Hyphen.docx (matches existing docs in Drive root)

Workflow: Write content as markdown → save to /tmp/whatever.md → run to-drive.sh → done in ~30 seconds.

Why: Building docs with python-docx takes 5+ minutes and 250 lines of code. This pipeline does the same thing in one command. Pandoc is installed on UDev.
