-    v1.1.0 - Improved file locking handling:
-    - Wait for file to stabilize (size stops changing)
-    - Exponential backoff retry (500ms -> 16s)
-    - Up to 10 retry attempts
+    v1.2.0 - Immediate processing:
+    - Process file immediately when eDNC releases it (50ms initial delay)
+    - Aggressive retry: 100ms -> 200ms -> 400ms -> 800ms (15 attempts)
     - Debouncing to prevent duplicate processing
+    - Exclusive file lock for atomic read/write
