Un-pack the 7-display cockpit in-engine (L4MFDSPLIT=1)

Browse Source 
The pod drove five monochrome MFDs from the color channels of two video
outputs - SVGA16 packs bit-slices of the shared gauge canvas into R/G/B
of gauge window 3 (upper MFDs) and R/G of window 4 (lower MFDs), with the
map palettized on the secondary and physically mounted portrait. The
desktop reconstruction previously required an external BitBlt-mirror
wrapper.

With L4MFDSPLIT=1, SVGA16 renders each display into its own window
(MFDSplitView, plain GDI) straight from the canvas + port bit-masks:
five green-screen MFD windows and the 90CW-rotated Map, tiled in the pod
grid to the right of the main view (L4MFDSCALE percent, default 50). The
packed D3D windows stay hidden but keep presenting off-screen, leaving
the original path untouched. Handles spanning mode (2-window setups).

Also: the plasma glass now opens directly below the main view (clamped
to the work area; L4PLASMAPOS=x,y overrides) per playtest feedback.

Verified: window grid comes up as main + 5 MFDs + Map + plasma with the
packed windows hidden; screenshots confirm a green MFD score readout and
the portrait tactical map rendering correctly. dist packer and BUILD.md
updated; the launcher wrapper is obsolete for split-mode use.
