When importing JSONL that matches the database exactly, import was reporting '0 created, 0 updated' which was confusing. Now it properly tracks and reports unchanged issues. Changes: - Added Unchanged field to ImportResult - Track unchanged issues separately from skipped/updated - Display unchanged count in import summary - Updated dry-run output to show unchanged count - Added test to verify correct reporting behavior Example output: 'Import complete: 0 created, 0 updated, 88 unchanged' Amp-Thread-ID: https://ampcode.com/threads/T-5dd4843e-9ce3-4fe0-9658-d2227b0a2e4e Co-authored-by: Amp <amp@ampcode.com>
