🔴 C++ static analysis fails on Ubuntu 26.04
On Ubuntu 26.04, clang-tidy adds an LLVM 19 repository for resolute, which apt.llvm.org does not provide. apt-get update fails, blocking the C++ Tools check.

The C++ Tools workflow builds an APT source URL from the runner codename in its Install clang-tidy 19 and clang 21 step. On Ubuntu 26.04, that codename is resolute. apt.llvm.org publishes llvm-toolchain-resolute-21 but has no llvm-toolchain-resolute-19, so the source added for LLVM 19 causes sudo apt-get update to fail before any tool installs. The Ubuntu 26.04 package repository itself provides clang-tidy-19 and clang-tools-19.
Example: A PR changing the CI workflow triggers the C++ Tools job on ubuntu-26.04. Its APT update requests llvm-toolchain-resolute-19/Release, receives HTTP 404, and stops before compilation database generation.
Recommended fix: On Ubuntu 26.04, install LLVM 19 tools from Ubuntu's repositories instead of adding the unavailable upstream LLVM 19 source. Keep the existing LLVM 21 source for clang-21 and libclang-21-dev, and verify the package installation and clang-tidy check on that runner.
