Fix left clicking input to edit

[willeastcott]

Do not propagate click events on input elements.

Fixes #91

[Copilot]

Pull Request Overview

This PR fixes an issue where left-clicking on input elements within graph nodes was not working properly for editing. The solution prevents click events on input elements from propagating to the parent node, which was intercepting these events and triggering node selection instead of allowing input interaction.

Key Changes:

• Added a new private method _preventNodeSelectionOnInput that stops event propagation on input elements
• Integrated this method into the input creation flow to apply the fix to all node inputs
