feat(launcher): show configured SSH host names in launcher rows

The new-tab launcher, Quick Jump and the command-palette SSH rows used
to render the raw destination (user@host) as their label, ignoring the
user-configured "主机名称" (host name) from SSH settings.

- Add ssh_host_labels() alongside ssh_host_icon_ids() and pass the
  label map into shell_palette_rows().
- Share a single ssh_host_display() rule across the launcher, Quick
  Jump and palette rows: a named host shows its alias as the label with
  the real destination as the metadata hint; unnamed hosts keep the
  previous label=destination, hint="SSH" presentation.
- Search now matches both the alias and the destination.

Tests: launcher rows with and without a configured name, including the
existing no-label fallback.
