Fixes thread-safety race in Utils.humanReadableByteCount.
Bug: static DecimalFormat TWO_DIGIT_FORMAT shared without synchronization, concurrent format() corrupts output.
Fix: wrap in ThreadLocal with withInitial supplier, use get().format() at call site.
Evidence: RED baseline and GREEN with fix both BUILD SUCCESSFUL on :clients:test --tests UtilsTest, no regression (race is nondeterministic under single-thread test).
