docs: sync plan with A-5 polish actually shipped (partiallyKnown filter, opacity split)

Final reviewer flagged that the plan still showed the pre-polish RecipeHint
shape and tierGroups pipeline. Update the plan code blocks to match HEAD
so future implementers see the shipped pattern (partiallyKnown field,
.filter(...) drop, undiscoveredDimStyle opacity wrapper, module-scope
MAX_UNDISCOVERED_PER_TIER).
