The `_perf/` measurement bench was gitignored and had never been committed, so 23 of the 27 scripts cited by the perf documents were already lost. The 11 surviving files (4 scripts, cfg_dm1.json, 5 result JSONs, the 53 MB MJPG clip) have been moved to D:\orisys_ws\docs\performance\perf-measurements\ and the scripts patched to resolve their defaults next to themselves. The directory has been removed from this repo. These three files said the scripts were deleted, which was only half true: they are moved, and the four surviving ones still run. Repointed: - src/orisys/sensor.py: the FILTER_PRESETS comment now names the real location (comment only; FILTER_PRESETS itself is unchanged). - docs/filters.md and examples/filters/README.md: the same correction for the latency/noise measurement provenance. No behaviour change.
