Consolidate dist/ into cache/ and release/ subdirs

All intermediate build artifacts (binaries, live-build work dirs, overlay
stages, NVIDIA/NCCL/cuBLAS/john caches) now live under dist/cache/.
Final ISOs go to dist/release/ instead of scattered dist/easy-bee-v*/ and iso/out/.
dist/ is already gitignored, iso/out/ entry removed as redundant.
