PLN's set work for CosmicFest, plus one new track and three mechanical fixes
found by the pre-gig gate.

His edits, across 23 tracks: the ^43/^44 -> ^41 control migration continued by
hand (37857225 retired gMask and freed ^41 for d1's gate), and real musical work
alongside it — a `resetCycles` head on rose_rouge, new `octersubbus` and
`squizbus` sends, a `slow 2 $ ply 2` rework of rose_rouge's ^54 line,
gain/lpf/room adjustments, and sample swaps (`n "74"` -> `n "25"` on the Savoy
break). New track: live/midi/nova/techno/livecode_parade.tidal.

Three fixes from the gate, none of which move a control number, so nothing
changes under his hands:

* mute map — d10 in something_about_drums declared gM2; the authored map
  (tools/lcxl_grid.py) puts d4-d12 on gM3. fix-mute-roles.py --apply, then
  re-run to confirm it converged to 0.
* crushbus 101 in ouais_je_funk was shared by d9 and d10, with DIFFERENT ranges
  (16->1.5 and 16->6) landing on one bus instance — last event wins, so the
  knob turned for one orbit was heard on the other. d9 moved to its own 91 per
  the <orbit><slot> convention.
* crushbus 41 in ghosts_in_the_toilets was shared by d4 and d7 the same way.
  d7 moved to 71.

pvlint goes 4 errors -> 0 on the setlist.

NOT included, deliberately: the remaining 20 column moves (ghosts 10,
something_about_drums 7, perfect 2, the_revolution 1). PLN: "migration i
unfinishe dgrrr lets not finish it before set for now." Renumbering which
physical knob does what in four tracks he plays tomorrow is a muscle-memory
change, not a safety fix, and two of the moves cannot resolve mechanically
anyway (one overflow -> gSel, one FIXME with no slot). gig-up stays honestly
red on `surface grid intact` until it is finished after the gig.
