Read-only (GET only). For each frameset: /api/raw/latest and /api/capture
of the same frameset_seq (retried until they match), the raw depth aligned
on the host with pyrealsense2 (software_device built from /api/intrinsics:
both streams' intrinsics, distortion model and coefficients, extrinsics
depth->color; then syncer + rs.align), and a pixel-by-pixel comparison of
the two aligned depths: pixels valid in both, only in one, exact-equal
fraction, |diff| mean/median/p99/max in mm. One JSON line per frameset.
The syncer may emit the first pair split, so a pair is pushed again (up
to 5 times) until a complete frameset of that frame number comes out.
