DreamNode template: minimalist README (title + describe-the-idea prompt)

The boilerplate README explained the whole UDD/holonic/Radicle model —
noise that buried the one thing that matters: a place for the user to
describe what the idea actually is. Semantic search indexes README
content, so a blank prompt ("Describe the idea here.") nudges users to
seed real content there instead of leaving generic boilerplate.
