Args field %s: arg:"inline" cannot declare public input tags

Error message

Args field %s: arg:"inline" cannot declare public input tags

What it means

Compile-time guard: an arg:"inline" field also declares public input tags (flag/schema/cli/doc/json). Inlined fields inherit their sub-struct's tags; public tags on the inline field itself are invalid.
