Inspector panel

Show the properties, shared styles, and bindings of the current selection in a side panel.

---

The panel is a plain React component rendered next to <Tldraw> rather than inside it. The editor instance is captured from onMount and passed to EditorProvider, which makes useEditor() and useValue() work outside the canvas.

With one shape selected it lists the shape's record fields and props, plus any bindings from editor.getBindingsInvolvingShape(). With several selected it shows editor.getSharedStyles(), marking styles that differ across the selection as mixed.

Try selecting a shape, then drawing an arrow to it and selecting the arrow to see its binding. Select several shapes with different colors to see mixed styles.
