Product recognition demo for supermarket shelf images

The deep review's first recommendation was real data, because every accuracy number so far comes from one or two photographs - the identity benchmark even takes its gallery and its queries from the same photo. This is the mechanism for replacing that. `--record-frames DIR` writes each processed frame, sampled every Nth, with a JSON line describing what the server saw in it: the boxes, the identity channels and the tag reading. The lines are the labelling input - `labelling_candidates()` returns the facings the tag channel named with a corroborated price, which are seeds for the confirmation screen rather than guesses. Nothing here is a training set on its own. Sampling keeps each frame's own number in the index, so a sampled recording says so instead of hiding it, and `/v1/health` reports how much has been written. Measured on a 163-frame walk: 32 frames and their lines. `docs/DATA.md` is the runbook: what to capture (a slow walk per rail, a close pass for the barcode, and the same shelf on a second visit), how to turn it into labels, and how to freeze a benchmark with a cross-visit split. 167 tests pass.
