Woonsocket's startup list covered: M32, SoundGrid link, MIDI on Macs without python

From the WS Production Startup checklist (check.watersmedia.org):
- M32 (the "X32" there is a Midas M32 at 10.2.1.146): Woonsocket's Companion got the X32/M32
  module (imported from NA's copy through Companion's own API) and an m32 connection; auto-setup
  names a single M32 connection's key M32.
- SuperRack's link to the Waves SoundGrid server: a soundgrid check builder (SuperRack's control
  connection on port 19000) inside every SUPERRACK key.
- MIDI ("Open Audio MIDI"): Macs without the Command Line Tools have their sessions read with
  JavaScript for Automation (coremidi.JXA_SESSIONS) - by the watchdog every 2 s and by discovery. A
  peer with no state (older macOS) counts as configured. A peer joined by name or IPv6 gets the
  wired address of the Mac whose session it is (matched by session name), at that session's port.
