claude-owner cab2ed13a3 feat(chart): Shift+Click adds horizontal line at clicked y-coordinate ...

H key and toolbar button use hover-or-last-close, so mouse users had no way
to drop a line at an arbitrary price they hadn't hovered. Shift+Click reads
the click's y via candle.coordinateToPrice — direct positional control.

- Plain click stays as native chart interaction (crosshair/drag)
- Only intercepts when shiftKey held; preventDefault to avoid text selection
- Honors the same 10-line cap as the H key / button
- ShortcutsHelp adds "Shift+클릭" entry next to H so it's discoverable
