Gahow Wang 7e91b83d88 Set PYTHONHASHSEED=42 for elastic mode to ensure consistent block hashes ...

Root cause confirmed: NONE_HASH = os.urandom(32) differs between
scheduler and bootstrap server even in the same process (init_none_hash
called separately by each import path). PYTHONHASHSEED makes it
deterministic: NONE_HASH = hash_fn(seed), same across all code paths.
