make gpu-worker: default to C tier

Browse source 
C tier is ~10× faster than Python tier on wire orchestration & has
the same primitives shipped this session. Python tier still available
for development debugging via LUMBDA=python; asm via LUMBDA=asm.

Auto-builds the chosen tier (c-build or asm-build) before launching
so a fresh clone runs cleanly without 'make c-build && make gpu-worker'
two-step.

Web page Start-a-GPU-worker subsection updated to match.
