Description

Right now, the SwiftUI API exposes one two-way binding for the editor's state: the current cursor positions. This change aims to expand the available bindings to allow developers to further control and customize the user experience.

Detailed Changes

• Adds new SourceEditorState struct, that organizes the bindings we publish into one place.
  • New Binding: scrollPosition - matches the scroll view's scroll origin.
  • New Binding: findText - matches the find panel text.
  • New Binding: replaceText - matches the find panel replace text.
  • New Binding: findPanelVisible - matches the visibility of the find panel.
• Adds new notifications to the find model and find controller, published when the find panel's text changes and when visibility is toggled.
• Adds a new notification to the text view controller that publishes whenever the scroll view changes.
• Updates the SourceEditor.Coordinator to receive the new notifications and update the state struct.
• Updates SourceEditor to update the editor's state when receiving an updated state struct.
• Updated README and related documentation to include usage examples.
