leonarski_fandClaude Opus 5.5 ddf41e3a18 CUDA JIT cache: a private one under /var/tmp when the default is unusable 
A service started by systemd without User= runs as root with no HOME, so
the driver keeps no JIT cache and every cuFFT plan is compiled again
(50-130 ms each, under cuFFT's process-wide lock) - seconds of MR in the
broker. Before anything touches CUDA, the broker and rugnux now point
CUDA_CACHE_PATH at /var/tmp/jfjoch-cuda-cache-<uid> when the default
cache is missing or unusable and the site has set no CUDA_CACHE_PATH.
The directory is used only if it is a real directory of this user's,
mode 0700; otherwise the start-up warning stays as before.

Measured without HOME: a cuFFT plan 51 ms -> 0.5 ms.
