Completes the humanize suite: - Clicks land on a jittered point inside the element's box (Fast/Human) instead of its exact centre. `resolve_element_center` now also returns the element width/height (box_model_dims); the CSS-selector path reports zero size → land on centre (no jitter, no regression). Jitter is clamped to the inner box so the click never misses. - Wheel scrolls split into eased, jittered segments (humanize::scroll_segments, unit-tested) instead of one instant jump. - Drag follows the curved trajectory at Fast/Human (linear 10-step at Off). Off is unchanged throughout. 9/9 unit tests; verified headless — jittered click still lands (→ iana.org), segmented scroll moves the page.
