Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert that the notice is above the panel.
Line 2063 only verifies that the token was written. A renderer that writes the boxed notice below the panel also passes this test. Compare the final token position with the final "Nuxt 4.5.2" panel header, and assert that the token precedes the panel.
Proposed test update
- await vi.waitFor(() => expect(strip(written())).toContain('gXSptCzfAzS2Lfgy'))
+ await vi.waitFor(() => {
+ const output = strip(written())
+ expect(output).toContain('gXSptCzfAzS2Lfgy')
+ expect(output.lastIndexOf('gXSptCzfAzS2Lfgy')).toBeLessThan(output.lastIndexOf('Nuxt 4.5.2'))

📚 Description
follows up on #1488
when nuxt/devtools (v3) asks for permissions, it prints a
logger.boxwith a URL to open and a token to paste:currently that gets hidden in the logs. likewise, startup warnings from the CLI itself are hidden.
this PR feeds both through the held-notice path #1488 added for
notify(): the box is written above the panel, where its URL and token can be read and copied, and anACTIONbadge takes the status badge's place until any keypress acknowledges it.
