Corpus from ~1.5 CPU-hours of libFuzzer on the save_walk target (650k+ executions across two runs, zero panics), minimized with 'cargo fuzz cmin' to 318 units / 786 coverage edges. Committing it makes future runs start from full coverage instead of rediscovering it. Also removes dbg_box_tab, a print-only debugging helper that slipped into the widget-test suite in PR #42.
