// markerRules maps a root-level marker file to the categories its
// presence votes for. A key containing a glob metacharacter (* ? [) is
// matched with filepath.Glob against the repo root; any other key is an
// exact filename. Weights are heuristic and tuned against the tests in
// this package — a single ecosystem marker rarely settles a category on
// its own, so the conventional-directory signals below usually decide
// the winner.
