- unit-stl_helpers.cpp: with a std::array argument, an unqualified bit_cast<...>(bytes) also finds std::bit_cast via ADL in C++20 and MSVC 2019 rejects the call as ambiguous (AppVeyor). Qualify the call. - comment_check_amalgamation.yml: skip, rather than crash, when the triggering run has no "pr" artifact (stale queued runs that complete as failed without ever running a job).
