Class FormattingService

Render the end-of-run "Changes" recap: a focused block summarizing what was created/updated/deleted, GROUPED by entity + operation with counts (no per-record IDs or field diffs — those scale poorly and live in the detailed report instead). One line per entity/operation means the recap stays compact whether 1 or 10,000 records changed. Returns '' when there were no changes (caller should skip printing).

For full per-record detail use --verbose (streams diffs inline during the push) or --change-detail (writes the report from formatChangesReport() to a file).

Render the FULL per-record change report as plain text (no ANSI), suitable for writing to a file via --change-detail. Lists every record's operation, entity, primary key, and — for updates — the field-level diffs.
