- README + README.zh: new Anti-detection subsections — "Human-like input
(behavioural stealth)" (curved trajectories / jitter / cadence / eased
scroll-drag, adaptive per-page escalation, off|fast|human) with the
trajectory contrast table, and "Silent operation" (background tabs, no
foreground stealing, focus-emulated). Added AGENT_BROWSER_HUMANIZE to the
tuning-knobs table.
- skill core: agents told operation is silent by default and how/when to use
--humanize (leave on auto; force human for known behavioural targets).
