📝 Full Task Prompt

### Objective
Remove semantic documentation drift from every canonical and public Nodes and node-flow page.

### Requirements
Update the stale user-dashboard-nodes and user-dashboard-node-flows canonical/public pages and generated registry descriptions to describe the project-scoped backend workspace, one-time localStorage import, registry-driven editing, publication, durable debugging, and the complete governed executable built-in list. Clearly distinguish planned and unavailable definitions from executable handlers. Do not claim unsupported production readiness.

### Verification
Search all docs and docs-web content for browser-local, non-executing, and six-node-only claims. Run check:docs-web and verify navigation links.
