Finishing a level showed a black screen forever: the engine kept running,
but the cutscene that follows the level (06a after Nar Shaddaa) never got
past its first frame. Ending a level shuts std3D down on the way to the
menus, and the cutscene player waits for std3D_IsReady() on every frame;
the ESP32 port cleared that flag at shutdown (the GL backend does not).
OpenJKDF2 330f270 makes the software renderer always ready.

Tested on the Tab5 with a local hook that ends each level after 20 s and
presses Enter through the menus: levels 1 through 8 and the cutscenes
between them (06a, 08-10a, 12a, 16a, 18-19a, 21a, 23a) in a row, no hang
or crash, free PSRAM at each level start between 1.5 and 2.6 MB with no
downward trend.
