Struct fakeMiddleware

proxy/internal/middleware/chain_test.go:16–29

fakeMiddleware is a minimal Middleware for chain composition tests. It records the metadata the dispatcher hands to it and emits a caller-supplied Output. Tests use the recorded snapshot to assert that earlier-in-slot emissions are visible to later middlewares.
