Structural generator mistakes surface at compile time via DSTG002-005
and partial-member matching, and emission regressions light up the
fixture suite - except one: dropping the reversed bucket scan in the
generated GetMinimumRequiredVersion compiles green and returns the
lowest enabled feature version instead of the highest, and the method's
only consumer is project-export LangVersion stamping, which default CI
runs barely exercise. Pin the highest-wins contract, including the
syntax-preference settings that now participate in the ladder.
