Tests bring the changed sources to full per-file coverage, the READMEs and
docs describe the uplink, the invocation context, and the Peer registry in
both languages, and the generated catalogs are refreshed.
Every Typert Remote stream accepts client-to-Host items on the same
logical stream. A method declares the uplink item type in its return
type, RemoteStream<Out, In>, and reads the items through
this.ctx.invocation.uplink(); the invocation also carries the calling
Peer. Client generated methods return a handle that iterates the
downlink and exposes send/end/dispose for the uplink.
