Eight commits of rig work that had accumulated on the branch while the shared
checkout sat on it. Reviewed as a diff, not taken on faith:

  perf.sh        stop DWIM-launching Pulsar into /usr/local/sbin -- 183
                 SIGABRTs between 08-19 and 09-05 because BASH_SOURCE resolved
                 to the deploy path, and the perf watcher re-entered every 30s.
  rig_units.py   neither LCXL painter may be auto-started blind; gig-up.sh's
                 generation-aware chooser owns that decision.
  midiviz        its own Wayland app id (desktopFileName, not applicationName),
                 so focus and KWin rules can name this window and no other;
                 plus the CC readout PLN asked for while wiring.
  logs 040/041   the phantom port, and the GIG UP rewire parked behind the
                 Ardour double-launch bug.

The four other branches were already upstream by patch-id.
