v0.8.2

Release v0.8.2

Proofreader improvements:

• Auto-reset batch state when re-running the proofreader on a file
  whose batches were all marked complete. Previously the tool would
  silently short-circuit with an internal 'batches complete' message
  which the coordinator paraphrased as 'file is clean'.
• Fix field-name mismatch in reset_batch_progress that left the
  proofreading completion flag stuck (proofread_complete vs
  proofreading_complete).
• Tighten the proofreader prompt: mandate paragraph-by-paragraph
  scan, override the shared 'quality over quantity' guideline, and
  require concrete verification evidence before returning
  NO_CHANGES_NEEDED.
