# lint.sh — Run all linters (clang-tidy + cppcheck + clang-format).

# Usage:
#   scripts/lint.sh                                    # All 3 linters
#   scripts/lint.sh CLANG_FORMAT=clang-format-20       # Override formatter
#   scripts/lint.sh --ci                               # CI mode (skip clang-tidy)
#
# This script is the SINGLE source of truth for linting.
