Static data-driven test covering 90 tools with 551 variations. For each
tool that has configurable settings, every enum value, boundary number,
and boolean flag is exercised through the HTTP endpoint. The test asserts
no 500s occur and validates response shape for 200/202 results.
Coverage spans image (29 tools), video (20), audio (15), PDF/document
(21), and data (5) modalities.
