Fixes the de-32 build break introduced by vibe-node #2912 (galileo 3.0.3 -> 3.0.8,
merged as bc4cecf). Job ad580587:
#16 chmod: cannot access '/0g/bin/0gchaind': No such file or directory
The Dockerfile hardcoded 'galileo -> mv <root>/rpc /0g'. That held for 3.0.3, where
every profile dir carried its own copy of the binaries. 3.0.8 DEDUPLICATED them into
a shared <root>/bin/ (168 MB -> 69 MB), leaving rpc/ as configs-only — so the move
produced configs and no binaries, and the build died two layers later on a chmod.
Note 'does <root>/rpc exist' is not a sufficient test: 3.0.8 still ships rpc/, it just
no longer holds bin/. Verified layouts:
galileo 3.0.3 <root>/{rpc,validator,archive,seed}/bin/ + configs
galileo 3.0.8 <root>/bin/ shared + <root>/{rpc,...}/ configs
aristotle 1.0.6 <root>/bin/ + configs, no profile dirs
So: take configs from the profile dir when present, then top the binaries up from the
shared root bin/ if the profile dir did not supply them.
Also asserts both binaries exist immediately after extraction, naming the chain, the
version and the known layouts — so the next upstream reshuffle reports itself at the
point of failure rather than as an anonymous chmod error.
Verified against the real artifacts — all three now yield an identical /0g
(bin/0gchaind 76M, bin/geth 46M, geth-config.toml, geth-genesis.json,
kzg-trusted-setup.json, 0g-home/, rollback_cl.sh), and a synthetic unknown layout
exits 1 with the diagnostic instead of reaching chmod.
