// Unit checks for src/util (text helpers, ansi) and src/config (consts, Config, tag resolution),
// plus the CLI help smoke. This is the surviving part of the old tests/test_main.cpp: its shell
// section is covered by tests/shell_test.cpp, its cli section by tests/cli_test.cpp, and its llm
// section exercised the placeholder llm API that the agent port removed (ChatClient("openai", ...),
// ModelHealth, Opencode, provider_info); the agent tests (agent_diff, agent_e2e) replace it.
// Plain asserts, so NDEBUG must stay off.
