Show live analysis progress in compare header

- analyze-file-path now fires compare-analyze-progress events with
  phase/percent/message (same data as the main analyze-progress channel)
- Compare header shows a thin progress bar + percent + phase message
  that updates live as the second file is scanned
- Cleans up the progress listener on completion or error
