Subject: [PATCH] fix(deps): pin warp-lang<1.18

warp-lang 1.18.0, released 2026-10-05, breaks the two required C++ test
jobs on every pull request. Its wheel is built for CUDA 13.4, which the
GPU runners' 12.2 driver does not support, so Warp sees no GPU. It also
dropped the config.quiet that nvalchemi-toolkit-ops sets before
warp.init(), so the start-up banner now lands on stdout and breaks the
LAMMPS tests that parse a subprocess's stdout as JSON.
