fix(workshop): bump @visa/nova-styles dependency to ^1.6.0

What

In apps/workshop/package.json, the @visa/nova-styles dependency is specified as:

"@visa/nova-styles": "~1.5.8"

but no 1.5.x versions ≥ 1.5.8 have ever been published. The latest available versions are 1.6.0, 1.6.1, and 1.6.2.

Why

• Users attempting npm install or pnpm install get a “No matching version found” error.
• The workshop app cannot bootstrap, blocking local development and CI.

Proposed Fix

Update the version range to match a published release, for example:

- "@visa/nova-styles": "~1.5.8"
+ "@visa/nova-styles": "^1.6.0"

Verify that apps/workshop installs, builds, and runs without errors.
