v2.8.6

Documentation accuracy pass over swipe and pinch, the same audit tap got in 2.8.5.

swipe's no-op diagnosis gained an outcome in 2.8.4 — on a screen with no React Native connection it reports that it could not inspect the screen — but every description still listed the old five causes as if that list were complete. Read literally, "could not look" became "no scroll view there": a claim about the screen, which is the exact confusion the code change exists to prevent. Corrected in the tool description, get_usage_guide(topic: "interact"), the tool reference and the README.

The device-interact skill pointed at a tool that does not exist. It told agents to call android_swipe (replaced long ago by the unified swipe) and stated "iOS: no dedicated swipe tool", false for as long as swipe has been cross-platform. Its text-entry section predated input_text / ios_input_text / dismiss_keyboard and had agents set values through execute_in_app instead. Rewritten against the registered tool list.

pinch was accurate everywhere; only its durationMs was undocumented, now listed.

No behaviour changes.
