IDE and editor support

• Visual Studio Code extension (very basic for now: just syntax colouring)
• GNU Nano syntax highlighting patterns
• Emacs mode (available from MELPA); needs tree-sitter support, which is included in Emacs 29 and later
• GEdit, the GNOME Text Editor and other programs that use GtkSourceView: GtkSourceView patterns
