The main change is in src/main/java/org/example/videoclips/queue/DatabaseBackedClipJobQueueAdapter.java:52: the DB queue now reclaims stale PROCESSING messages after a configurable visibility timeout instead of leaving them
stuck forever after a worker crash. I added video-clipping.database-queue.visibility-timeout-ms with a default of 900000 ms in src/main/java/org/example/videoclips/config/VideoClippingProperties.java:171 and src/main/
resources/application.properties:19, plus coverage for stale-claim recovery in src/test/java/org/example/videoclips/queue/DatabaseBackedClipJobQueueAdapterTest.java:91. I also added the tuning note and sizing rule in docs/
queue-visibility-timeout-tuning.md:1.
