Add-preview-version-output

[shahsimpson]

Fixes BANDA-1738

Building atop #12983

This change adds a preview output entry to Wrangler’s output file stream, so wrangler preview writes structured preview metadata (preview id/name/slug/urls) alongside its linked deployment metadata (deployment id/urls).
The goal is to make output-file consumers (Builds) able to reliably read both preview and deployment URLs from JSONL output, without scraping CLI text output.
