描述

Holding Shift and creating a line tool constrains the line to a discrete angle. It would be ideal to have a similar functionality for freedraw elements, where when Shift is held, the freedraw drawing is straight and constrained to the same discrete angles, like with the Shift + line tool. It would mirror the behavior in Photoshop.

研究方向
Look at the line tool's angle constraint implementation in excalidraw's codebase, likely in the shape or tool files. The freedraw tool's drawing logic needs to detect Shift key and apply straight line segments constrained to discrete angles. Check existing angle snapping constants and how they are used. The implementation should mirror the behavior of the line tool when Shift is held.
