sync template with WebOS desktop 0.6 and SVG icons

[Xuepoo]

The scaffold template is stale: both template-owned/package.json and generated template/package.json pin @vectojs/desktop 0.4.0, while WebOS now requires 0.6.0 for iconSvg and stable SVG chrome. Re-sync template/ from the current WebOS repo, update generator-owned dependency metadata, add scaffold assertions for iconSvg/legacy icon removal, and run generated-project gates.

Completed by PR #2. The scaffold template now tracks WebOS desktop 0.6.0, stable iconSvg definitions, responsive layouts, and interaction-state updates.
