Addresses #37.

This updates the existing roadmap facts without starting the post-GA site revamp: Pithead v1.20 is the latest shipped line, develop is the integration branch, and Pithead OS 2.0 remains explicitly marked “In review.” The broader appliance download and installation rewrite stays deferred until 2.0 ships, as the issue requires.

Validation:

• confirmed the develop branch through the GitHub repository API
• confirmed v1.20.0 is the latest published Pithead release
• searched data/content.yaml for develop-v2 and stale v1.19 release copy; no references remain
• npm run lint passed
• strict Hugo build passed with --gc --minify --panicOnWarning
• git diff --check passed
• independent Luna/high docs review passed at 96c98c044effb2849e88cd7d9e8a4761ed2f4f68

htmltest was unavailable locally; CI remains the link-check gate.

Non-author source decision: PASS at exact head 96c98c044effb2849e88cd7d9e8a4761ed2f4f68.

Independent Luna/high verification passed this documentation-only change. Root read the diff: the roadmap refers to develop and shipped v1.20.0 while keeping the appliance in review. Local lint and strict Hugo build passed; local htmltest was unavailable. All nine current CI checks passed, including build-and-check and Lighthouse. Public diff and prose scans are clean. The broader post-release website work in #37 remains open.
