Detailed Description

Fixed-capacity streaming oscilloscope trigger and capture.

Capture windows contain pretrigger_samples samples before the trigger, followed by the trigger sample and the configured post-trigger tail. Edge modes use a level plus hysteresis and can run once or continuously with an exact sample-count holdoff. Continuous acquisition keeps the most recently completed frame published while the next frame is in progress. Processing is allocation-free, lock-free, and independent of caller block partitioning. capture_completion_latency_samples() is acquisition readiness after the trigger sample, not signal-processing or host-compensation latency. capture() exposes same-thread state only; callers must provide their own synchronized snapshot/mailbox when publishing frames across threads.
