# CodeQL security analysis (C++ engine + Python tools).
#
# Runs on pushes to dev, weekly, and on demand -- not on every PR -- because
# the C++ analysis requires a full instrumented build (~40 min). The SARIF
# results appear under Security -> Code scanning and are also posted as PR
# comments when a PR branch is analyzed.
