L'électron rare

Add generate_live_variant_sc() to produce 4 deterministic live
variants per style (112 files). Each variant differs by:
- pattern family (VARIANT_FAMILIES per style group)
- era instrument kit overlay (house/M1, acid/hoover, virus/nord,
raw 909/rave) merged from VARIANT_ERA_KITS
- busy-block recolour config (VARIANT_BUSY, 4 distinct profiles)
Also: fix generator defaults to match live state:
- globalActions: fill/doubleTime/washReverb/muteDrums/relanceEvolve/
halfTime/next/muteMelo (was fill/drop/breakdown/evolve/...)
- hand-mod depths 0.70 (was 0.40/0.50 for rHandX/rHandY/lHandX/lHandY)
- INST_CHOICES synced with matrix.scd ~matInstChoices (10 new vintage
synths: tr909_snare hoover m1_piano m1_organ dx7_epiano brass_stab
nord_lead virus_saw rave_stab reese_juno)
Update test_global_actions.py to expect new 8-action mapping.
Add test_live_variants.py: 112 files, legal instruments, distinct
variants, determinism.

Load Order
CHARGER TOUT charge automatiquement dans l'ordre :
- engine.scd
- synth/_index.scd + fx/_index.scd (auto-loaders recursifs)
- palette/scales.scd (scales + helpers melodiques)
- palette/melodies/index.scd (130+ melodies + multi-track)
- palette/harmonics/index.scd (~enableHarmony + helpers)
- palette/rhythm/fills.scd (snareFill, tomFill)
À évaluer manuellement (Cmd+Entrée bloc par bloc) :
- live/live.scd SETUP (LFO, VCF, tricks)
- live/mixer.scd SETUP (faders, mute, solo, master)
- live/fx_bus.scd SETUP (FX bus, presets)
- live/loops.scd SETUP (loops manager)
- live/scenes.scd SETUP (snapshot/recall)
- control/midi.scd INIT + MAPPING DEFAULT
