ci(docker): identical, more aggressive disk reclaim in both image jobs

The two builds flip-flopped against the runner disk ceiling: CUDA hit
ENOSPC this morning (fixed by adding the reclaim step), then ROCm hit it
this afternoon even WITH the original list. Reclaim everything neither
job can use (~40-45 GB: full hostedtoolcache, swift, boost, global
node_modules, apt cache) and keep the list byte-identical in both jobs
so they can't drift apart again.
