JavaScript refactoring Renaming a variable

### Description

Is there a plan to add at least a draft version of variable refactoring for JavaScript to the environment?
I think that when refactoring, a window with drains and checkboxes should be created in advance, where it is suggested to make a replacement, and the user could use checkboxes to choose where to make the replacement and where not. A regular replacement would be suitable for this approach.

Overall the JavaScript editor is lightweight and fast, but it lacks refactoring.

The issue names no files, tests, or entry points; begin by locating the JavaScript editor and any existing refactoring support in NetBeans. Done would require an agreed scope for variable renaming and a defined replacement-selection workflow, followed by corresponding implementation and tests.
