M3.17: interactive gradient annotator — drag the start handle or the bar to move the gradient, the end handle to change length and angle, just past the end to rotate (Shift snaps to 45°); a bar click adds a stop, stops drag along the bar, off it to delete (never below two), Alt-drag copies, diamonds move midpoints; a click inside selected art applies the gradient from that point; double-clicking a stop opens a popover (Color/Swatches, Opacity, Location); the selected stop lives in the session (gradient.selectStop), shared by the tool, the Gradient and Color panels and agents, and takes Delete/Backspace and ←/→ ahead of their shortcuts (Tool::claims_key, also headless); stop chips draw as Overlay::Swatch with generated add/remove-stop cursors; the stop math moves into the color crate
