# Bootstrap development environment and prepare build directories.

# bootstrap.sh pulls LLVM from apt.llvm.org, which intermittently rejects
# requests from CI runners; llvm.sh then reports either "GPG key not
# reachable" or the misleading "Distribution 'debian' ... is not supported"
# (its HEAD probe of apt.llvm.org/<codename>/ failed). bootstrap.sh is
# idempotent, so retry it a few times with a pause instead of failing the
# whole multi-hour pipeline on one flaky request.
