v0.10.2

Fixed

• use, sync and prune no longer print a bare ok <app> line for an app that was already
  in sync. An empty change list was rendered as nothing at all, leaving a row of trailing
  whitespace that read as a truncated or failed result; it now says unchanged, which is what
  a repeated sync actually did.
• Codex states the Responses requirement only when the endpoint has not declared itself
  Responses-compatible. The caveat was printed unconditionally, so a provider the user had
  already marked responses — where there is nothing to warn about — warned anyway, and a
  fully successful sync looked like it had a problem.
• Syncing to a machine whose agent configs do not exist yet no longer prints a backup: … line
  when nothing was backed up. A transaction directory was created for every commit even when
  every planned file was new, so on a first run the output announced eight backups that held
  nothing but a manifest.
