Merge remote-tracking branch 'origin/master' into feat/web-message-feedback-ui

Adapt to two contract changes master introduced:

- The generated Remote face now wraps every business result in
  RemoteResult, folding carrier failures into an ok:false branch instead
  of rejecting. The controller reads that envelope at its three call
  sites and maps a carrier failure onto the same settled shape the
  controls already render; three specs cover the new branch.
- Client packages split their tsconfig into host and client halves, and
  the host aggregate now compiles any test not named *.client.spec.*.
  Rename this package's specs to the client convention and drop the
  ../connection project reference, which pointed at a solution file that
  no longer carries the client sources.

Keep master's mount loop with its rollback-on-failure in api-remotes and
add messageFeedbackRemote to it.
