Jump tunnel fixes

Ship the x64 client and renderer from REM-Client
c238ef4a6b2386ba0dd4016951dbd22df267397f.

Update gate tunnel colours, alpha controls and scrolling/twist parameters;
add a separate violet jump-hole profile and matching background fades.
Include the compiled renderer, detail tiers and corrected build provenance.

Verified all 11,143 runtime/data files against the Lutris installation,
five completed singleplayer jumps, four detail levels and options Save.
GPU regressions passed on NVIDIA and Intel; player saves/settings were
restored unchanged. Multiplayer flight remains untested.
