BenStullsBets 0548e9a82b feat(sim): two-element audio crossfade keyed by scrub fraction

Per plan Task 2. Adds <audio id=aud-b>; blendAudio(lo,frac) mixes the two
adjacent scale soundtracks by knob fraction (element reuse across crossings so
only the genuinely-new scale reloads); restAudio settles a single scale at rest.
Diagnostic readout now reports whichever element is audible.

Simulator unit tests

Pure-logic JS unit tests (no browser), run with Node's built-in test runner:

node --test simulator/unit/*.test.js

scrub.test.js covers simulator/static/scrub.js — the pure altitude-scrub math (position→segment, frac→currentTime, audio gains, integer-crossing detection).
