Bind and BindEmpty fill Req from path/query/json struct tags and validate
once, extending the typed decode->validate->call->encode pipeline to routes
with identifiers and filters. Conversion via builtins + encoding.TextUnmarshaler
(uuid.UUID, time.Time); malformed value -> 400 naming the parameter; default:
applies only when absent; repeated query -> slice; mis-tagged struct panics at
wiring. Purely additive; existing adapters unchanged. Coordinated lockstep v1.6.0.
