Add clang build configuration to catch C++20 compatibility issues early. Changes: - Add build-clang job to .github/workflows/build.yml - Add missing #include<cstdint> for std::uint* types (clang strict mode) - Add -lexecinfo for FreeBSD in configure.ac (backtrace_symbols) - Fix pessimizing-move warning in test_earningsrebalancer.cpp - Fix CHANGELOG.md formatting 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
