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

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}.

+### 1. Cache has no size limit
 
-`WithCache(ttl, maxEntries, maxBytes)` can now bound the cache by entry count and approximate
+`WithCache(ttl)` stores all successful GET responses in memory with no maximum entry count or
