Initial import: Tesla Release 4.10 (Tesla:BattleTech & Tesla:Red Planet)

Archival snapshot of the Virtual World Entertainment Tesla cockpit
software, 1994-1996: MUNGA engine and L4 pod layer source (Borland
C++ 5.0), BT/RP game code, and game content (models, audio, maps,
gauges, Division renderer data). Includes third-party libraries:
Division dVS/DPL graphics, HMI SOS audio, WATTCP networking.

Files are preserved byte-for-byte (.gitattributes disables all
line-ending conversion). README.md documents the layout, target
hardware, and toolchain.
