Add product judgment research artifacts

[kentcdodds]

Summary

• Add a product judgment research workspace under instructor/product-judgment-research/.
• Add scenario cards for the strongest loops from the Kody stash, including MVP triage, evidence weighting, decision rights, prototype-as-spec, enterprise pressure, feature framing, migration pain, API/DX judgment, fog-of-war experiments, and AI-era buy-versus-build.
• Add raw-example capture, decision-record, follow-up contact, and outreach prompt templates.
• Link the workspace from instructor/notes.md so future workshop/content work can find it.

Confidentiality

• The buy-versus-build material is generalized and explicitly marked as confidential/anonymized.
• No person, employer, industry, or specific private DM details are included for the confidential source.

Next Steps for Kent

• Start follow-up with the direct-pain and high-signal sources in follow-up-contact-list.md.
• Test the decision-record-template.md in one or two interviews before turning it into an exercise artifact.
• Promote the strongest scenario cards into workshop exercises after validating which loops resonate most.

Validation

• npx prettier --check "instructor/product-judgment-research/**/*.md"
• git diff --check
• Confidentiality grep for identifying buy-versus-build source terms returned no matches.
