Enable file renaming via double-click in the sidebar

Increasing Access

This feature adds support for renaming files in the p5.js Web Editor by double-clicking on a file name in the sidebar. This mirrors common UX behavior found in most modern code editors (e.g., VS Code, Atom), making the workflow smoother and more intuitive.

This feature increases access by supporting a more familiar and discoverable UX pattern for users of all experience levels and minimizes reliance on right-click menus, which are less accessible on touch devices or for users who prefer keyboard/tap-based workflows.

Feature enhancement details

It should listen for onDoubleClick on the file name button and trigger the existing rename logic.
