Improvements to nuxt analyze:

• --name keeps each run: each run is written to <analyzeDir>/<slug>/, so you can compare runs (for example --name=before and --name=after).
• --json: writes client.json and nitro.json (raw-data format of rollup-plugin-visualizer) instead of HTML, and does not serve them. Good for scripts and AI agents. It also turns off the Nuxt DevTools .vite-inspect output, which only the DevTools UI uses.
• Nitro report with Nuxt 5: Nitro v3 has no analyze option, so no Nitro report was written. The CLI now adds rollup-plugin-visualizer to the Nitro build when Nitro did not.
• Stats server: links only to the reports that exist, and serves the report directly at / when there is only one.
• webpack/rspack: the build no longer opens the report in a browser, because the CLI serves it.
• If the port 3000 is already taken, it fallback to the 3000-3100 range instead of erroring

Reject --name values that collide after slug sanitisation.

--name=after/fix and --name=after_fix both produce the slug after_fix, so the second run clears and overwrites the first run's reports. Before clearing the directory, check whether an existing meta.json records a different name, and throw an ActionableError if it does. Otherwise, document that names collide.

Before clearing analyzeDir for the slug derived from --name, check whether its

⚠️ Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The documentation describes --json as producing visualizer raw-data without limiting that promise to Vite, whereas the supplied PR context says webpack already produces client.json stats. Those formats may not be interchangeable.

A documented consumer cannot find the promised module, chunk, and import fields in the stated format.

This can occur when: Run --json with the webpack builder and process client.json as visualizer raw-data.

Add assertions for both report routes.

The two-report test checks only the links in /. Add requests for /client and /nitro, and assert that each response contains its report content rather than the index. The current single-report route test does not cover this case.

Extend the `should link to each generated report` test to request both `/client`

corresponding report content rather than the index page. Keep the existing
assertions for the links in `/` and use the report content already provided by

⚠️ Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The new browser-opening override is set only under webpack.analyze; rspack may use a separate analyzer setting and continue opening its report.

A browser opens despite the CLI disabling serving and intending to suppress builder-opened reports.

This can occur when: Run nuxt analyze --no-serve with the rspack builder if its browser-opening option is not inherited from webpack.analyze.

in the build note as well, so the stats server links to the report that was
