Balance loop 3: the anchors claim the synthesis-depth machinery

b328159 shipped hi-gain staging, filter envelopes, and tempo-synced LFOs with no anchor claiming them. Nineteen anchors now do:

• HIGAIN, the metal wing (per-archetype stage/tone, replaces strip distort where it stood): heavymetal (2-3 stages, the wall), longshipwhip (thrash TIGHT-GATED, mid-scooped, gate .55-.8), sludgemetal +…

FENV — electro bass+lead and acidhouse's pluck-lead seeds claim the unified fenvAmount/fenvDecay (the legacy multiplier fenv removed on those voices so envelopes never stack; tb303 keeps envmod).

• LFO sync: dubstep wobbleBars .125 (THE 1/8 wobble, was free-running 1.5-4.5 Hz), italo juno60 pwmBase/pwmLfo, trance pad tremolo gate at a 1/16 (rateBars .0625, shape .7-1).

WAH TRIM — disco/newjack/picnicswing/ chromeufo wah mix ranges -> .6-.7 (full-wet trimmed sampled funk bass ~3.9 dB).

Verified: verify.sh --no-cache fully green (matrix 228/228 + validate + engine + prove + matproof); probes higain/fenv/lfo-sync all PASS; theory/pipes/meter/musicality/invariants PASS
