docs: the environment side needs neither CUDA nor a GPU - #12

The home page said a VLA runs end to end through the boundary and stopped there. The result worth arriving for is what the environment side now costs: 3.4G with no nvidia wheels instead of 7.8G with sixteen, rendering on the CPU, ten clients, 30 of 30 episodes, at 1.91x wall clock. The section leads with that and then gives the catch, because 1.91x is the difference between a measurement and a slogan. It also says plainly that this overturns E1, which had concluded the opposite from a default install.

The home page stopped at a VLA ran end to end through the boundary. Since then two experiments measured what the environment side actually costs, and that is the part a reader can act on.
The new section, in both languages
It also says what it overturns
E1 measured a robomimic-class env client at 7.2G with CUDA and concluded the environment side does need a GPU. That was true of a default install - on Linux
torchbrings CUDA whether or not anything uses it. E12 reproduced E1's row exactly before changing one pin, which is what makes the two comparable, and E13 measured the rendering cost.mkdocs build --strictpasses.
