Revisit 6 tracks with new pytheory 0.40.9 synths

Ghost Protocol: arp → drift (analog wobble)
Deep Time: shimmer → drift, added granular_pad grain layer
Voltage: added hard_sync part at bar 49
The Interruption: reese bass → drift (analog menace)
An Exception Occurred: added ring_mod during psychosis
Intrusive: thought → wavefold with organ envelope (uglier, harder)
