Incorporates 5 lessons from commit 216f3a4 into the plan:
- Connection keys/targets must use node names, not IDs
- HTTP auth must use Header Auth credential, not manual env vars
- Node names must be unique
- Use $('Node Name') after GraphQL chains, not $input.item.json
- Added validation checklist to verification section
Marks Task 2 as already completed (dead code removal done in hotfix).
Updates node counts from 193 to 181 baseline.
