+Chunker pipeline — splits files into chunks, processes concurrently, reassembles in order.
+
+Public API:
+    Pipeline      — orchestrates the full pipeline
+    PipelineResult — aggregate result dataclass
+    Chunker       — file → Chunk generator
+    ChunkQueue    — bounded thread-safe queue
+    WorkerPool    — manages N worker threads
+    ResultCollector — heapq-based ordered reassembly
