Transit arrival: crossed genres get their instruments (the flute exorcism)

Paul: "Moving from blues to industrial we hit dnb. It's loaded but the promised instruments don't show up.

• The blend-arrival fix's tiered flip queue kept a journey-scoped never-applied memory, cleared only on convergence — which never happens during continuous travel.

• Fix, ~3 lines: the never-applied memory clears when the DOMINANT genre changes, so each new neighborhood's identity flips (form / drum kit / lead voice) re-enter tier 0 and land within ~6 bars of dominance

Verified: transit-arrival-run.js is the committed contract (pre-fix FAIL confirmed): dnb lead arrival rel 16 -> 0, kit rel 18 -> 2, lead held 18 bars, 10 rhodes note() calls the first melody-on bar.
