v2026.5.19

Changes

• WeChat: implement dynamic relative coordinate geometry calculation for sidebar buttons, message inputs, chat avatars, and scroll areas to prevent resolution-dependent drift on Retina screens, external displays, or drag-and-drop actions.
• Peekaboo: add the peekaboo-wechat skill with strict atomic tools, forbidding fallback to keyboard/mouse CLI macro simulation.
• Web client (webds): optimize stream rendering by filtering nested chunk signals and high-frequency stream events.
