Plasma display: send the real clear+home; bump suite to 4.11.4.4

Browse Source 
The provisioning text on the pod's plasma panel came up garbled — stale
content bleeding through, new text overlapping at the wrong position.
Root cause recovered from the dumped PD01D221 controller firmware
(vrio/PlasmaNew): PlasmaWriter.ClearAll() sent ESC J, which on this
controller is NOT a clear — it toggles an orientation/mode bit — so the
panel never cleared and the cursor never homed.

Fix: ClearAll() now sends the real commands ESC @ (clear active buffer,
reset text state) + ESC L (home to 0,0), and the writer hides the cursor
once at open with ESC G 0 — exactly what the game and the ROM's own demo
do. Verified by running the launcher's actual byte streams through the
firmware-modeled vPLASMA emulator: the old ESC J path left stale pixels
(732 lit vs 404); the new path renders byte-identical to a freshly
cleared panel (404 lit, cursor hidden).

Version bumped 4.11.4.3 -> 4.11.4.4 across Launcher, Console, vPOD, the
install/build banners, and the diff-suite version assertion. This cuts a
clean release boundary that also carries the earlier field fixes
(process-tree kill on Stop, Win10 install.bat icacls quoting, real system
volume + pre-uninstall opt-in, and the volume menu check-mark fix).
