Zero-config preview flow cli.js, README.md, CHANGELOG.md, test/cli.test.js	The CLI accepts --zero with --dry to preview current-directory processing without writing files. The preview reports processing statistics. Help text, documentation, and tests describe and verify this behavior.
Terminal and option guidance cli.js, CHANGELOG.md, test/cli.test.js	Interactive stdin displays instructions for ending input and choosing a processing mode. Dry-run and verbose output suggest --preset=comprehensive when no minification options are set.

Backtest interrupt message

Full details: Title check

Explanation

The title "Improve CLI defaults and handling" is related to the changeset, which changes CLI behavior around zero-config mode, dry-run previews, stdin guidance, and preset suggestions. It is broad, and it does not name the main change (zero-config dry-run preview). It is a real aspect of the change, so the check passes as partially related.
