// WasmPluginsRerouteMatchRule tests that wasm plugin matchRules work correctly
// after a reroute triggered by a previous plugin (issue #3571).
//
// Scenario:
// - Ingress "reroute-match-default": host reroute-match.com, path /, no header constraint
// - Ingress "reroute-match-target": host reroute-match.com, path /, header x-user-id: 1
// - Plugin A (transformer, priority 400): matchRule for "reroute-match-default",
// maps query param "userId" to header "x-user-id", causing reroute
// - Plugin B (custom-response, priority 200): matchRule for "reroute-match-target",
// returns custom response {"hello":"world"}
//
// When sending GET /?userId=1, plugin A adds x-user-id:1 header and triggers reroute.
// Plugin B should see the NEW route "reroute-match-target" and return the custom response.
