Pure formatting, no behaviour change. PKG landed .clang-format (Google base, 4-space indent, 100 cols); this brings util/ and the test harness into conformance so `clang-format --dry-run -Werror` is clean. Build and all six test binaries unchanged and green. Co-Authored-By: Claude Sonnet 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HPPSGhiArbvQgwC2DNiURS
