fix(gig): boot the real start_and_midi.scd, not stale main_fairbanks — root of silent synths & orbit errors

gig-boot.scd chained main_fairbanks.scd (scratch: 8 output channels, 8 orbits)
BEFORE start_and_midi.scd. main_fairbanks booted the server first, so PLN's
real boot found it already up and its options were ignored — losing the 28
channels, 14 orbits (d1..d12 + ears test), SCLOrkSynths.load, the MI global
effects, StageLimiter + s.volume=2. Net live: d9-d12 silent, bassWarsaw/
FMRhodes1 never loaded, orbit 8/10/11 errors spamming the post window.

Fix (#18 simplification): launcher runs PLN's canonical sclang start_and_midi.scd
directly; gig-boot.scd retired; main_fairbanks.scd kept as reference only.
Apply = FULL sclang/scsynth restart (running scsynth keeps 8-ch options).

gig-boot.scd

-// gig-boot — canonical 1-click gig boot, loaded by gig-up.sh.
-//
-// Runs the real SuperDirt boot (main_fairbanks.scd: server + SuperDirt on :57120 +
-// MIDIClient.init + note handlers) followed by the LaunchControl XL CC->OSC bridge
-// (start_and_midi.scd — the fader/knob handlers). One eval = a fully armed rig.
-//
-// gig-up.sh runs this, then waits EXTERNALLY (scsynth up + :57120 listening + a
-// SuperCollider ALSA-seq MIDI client present) before it starts Ardour — so Ardour
-// can never grab the LaunchControl before SuperDirt has, killing the old
-// disconnect/reconnect dance. Loaded by relative path so the repo stays portable.
