Disable summary for default reporter via cli

Clear and concise description of the problem

We use CLI to run tests in CI
vitest --run --reporter=basic --reporter=github-actions

But the basic reporter is deprecated and tests output

DEPRECATED  'basic' reporter is deprecated and will be removed in Vitest v3.
Remove 'basic' from 'reporters' option. To match 'basic' reporter 100%, use configuration:
{
 "test": {
   "reporters": [
     [
       "default",
       {
         "summary": false
       }
     ]
   ]
 }
}

It is much easier to configure Vitest via CLI rather than using a config file in our pipelines. So we would like to configure the reporter via CLI.

Suggested solution

Add CLI option --reporter.summary. This option may affect all reporters

Alternative

Or add options parsing and matching them with reporters by name, for example --reporter.default.summary=true, --reporter.verbose.summary=false

This format may work for other reporter options in the future

Validations

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that request the same feature to avoid creating a duplicate.

Start by tracing Vitest's CLI parsing for the --reporter option and how reporter configuration reaches the default reporter. Compare the proposed global and reporter-specific option formats, then verify the example command. The work is done when the selected CLI form disables the default reporter summary without requiring a config file and its behavior is covered by tests.
