/**
 * Parser for Express 5 / `router@^2.x` apps.
 *
 * Strategy: walk the router tree, joining captured mount paths
 * (recorded by the `instrument` patch) with each `route.path`. Path-parameter
 * extraction uses path-to-regexp v8's `parse()`, which exposes the structural
 * AST (`Text | Parameter | Wildcard | Group`). We walk the AST per layer and
 * accumulate parameters across nested mounts so the leaf route reports its
 * full ancestor chain, matching v4 behavior.
