clang_format.sh

#!/bin/bash
# Apply (or, with --check, verify) our clang-format style across all first-party source files.
# Vendored / third-party code that isn't formatted to our style is excluded via the pathspecs below.
#
# Usage:
#   ./clang_format.sh          Reformat all first-party source files in place.
#   ./clang_format.sh --check  Verify formatting without modifying files (non-zero exit on diff).
#
# The file list is emitted NUL-separated (git ls-files -z) so paths with spaces are safe.
