gpu-worker: fork-per-accept + VRAM-aware admission 
Single-PID parent persistent listener; each accept forks a short-lived
child handler that owns one bend-cuda subprocess + responds + exits.
Linux COW handles memory; OS scheduler distributes across cores.
N concurrent requests = N children + parent — naturally VRAM-isolated.

VRAM admission: wait-vram-clear queries nvidia-smi before each fork,
blocks accept when used > *vram-budget-mib* (default 22000, override
via LUMBDA_VRAM_BUDGET_MIB env). 24G card with avg 1-2GB per bin
supports 4-12 concurrent comfortably.

Requires lumbda c-tier fork-self / waitpid-nonblock / exit-immediate /
sleep primitives (commit 81ac49e). Child uses exit-immediate not exit
to avoid dual-cleanup hang on shared parent state.
