PHLEGM v8 Checkpoint 63 - Console prompt icons

A direct console instruction with a command-bearing leaf is displayed as a right-facing caret followed by a solid black block cursor.
Windows uses GUI_ICON_CONSOLE=8 with a shared black cached GDI bitmap.
Linux uses native icon kind 7 with one cached Cairo pixbuf per type.
Media, CHIPSET/SUPPORT, CHR, FIRMWARE, ZIP and folder icons retain precedence.
Runtime behavior is unchanged; no FreeBASIC native compiler was available for validation in the patching environment.
