Pull request overview

Updates auto-update output formatting to report results grouped by config entry (project config file → repo), including per-entry details like rev line numbers and clearer “frozen comment” messaging.

Changes:

• Reworks auto-update display logic to emit structured events and render grouped, stable output (including per-entry line numbers where needed).
• Adjusts frozen-comment mismatch handling/output wording (e.g., “frozen comment” vs “frozen reference”).
• Updates integration test snapshots to match the new stdout/stderr format.

Reviewed changes
