ci: use Debian Trixie for macOS cross job
This will use Clang & LLVM 19.
What changed, and why it matters
This commit only changes which Linux container image is used for Bitcoin Core's automated macOS cross-compilation testing jobs, switching from Ubuntu 24.04 to Debian Trixie in order to use Clang/LLVM 19. It does not modify any wallet, networking, consensus, or node code that end users interact with, and it introduces no apparent security issue.
No security action required. Treat as a routine CI infrastructure update.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff updates two CI environment setup scripts (ci/test/00_setup_env_mac_cross.sh and ci/test/00_setup_env_mac_cross_intel.sh) to set CI_IMAGE_NAME_TAG to mirror.gcr.io/debian:trixie instead of mirror.gcr.io/ubuntu:24.04. The accompanying comment explains the goal is to verify that Debian Trixie’s clang package (version 19) can cross-compile for macOS. No other variables, package lists, or build logic are changed.
