chore(api): AX compliance sweep — banned imports, naming, test coverage

Browse source 
Replace fmt/errors/strings/encoding/json/os/os/exec/path/filepath with
core primitives; rename abbreviated variables; add Ugly test variants to
all test files; rename integration tests to TestFilename_Function_{Good,Bad,Ugly}.
