Feature Request: add prop for sharp edges in generateStageSvgPathString function

Hey team,

I have a suggestion for the generateStageSvgPathString function. It would be great if we could add a prop to the StageDefinition interface to allow sharp edges for the highlight box. Right now, it only supports rounded edges with stageRadius.

Proposed Change:

Add a sharpEdges prop to StageDefinition. If sharpEdges is true, the function should generate sharp edges instead of rounded ones.

Example:

const stageDefinition: StageDefinition = {
  x: 100,
  y: 100,
  width: 200,
  height: 200,
  sharpEdges: true, 
};

const pathString = generateStageSvgPathString(stageDefinition);

This would give more flexibility in how the highlight box looks. Let me know if this is something you'd consider. Happy to help with a pull request if needed.

Thanks!

Best,
Aga

Search the TypeScript definitions for StageDefinition and the implementation of generateStageSvgPathString. Trace how stageRadius currently shapes the highlight box, then verify that a StageDefinition with sharpEdges: true produces sharp corners while existing rounded-edge behavior remains unchanged.
