Patch Changes

• Add IPython Cell Magic for HMR (#594)

  New %%vfile cell magic for prototyping widgets in notebooks. Enables syntax highlighting and anywidget's Hot Module Replacement (HMR) directly within the notebook.

  Previously, front-end code had to be inline strings or file paths, causing loss of widget state when editing inline-strings in notebooks. The new %%vfile cell magic allows editing front-end code within the notebook with live reloading on cell re-execution.

  Use %%vfile <filename> to create a virtual file for either JavaScript or CSS, and use vfile:<filename> in _esm or _css attributes of an AnyWidget subclass to reference the virtual file. Anywidget applies HMR updates automatically on cell re-execution.
