Subject: feat(mq_editor): add iso-contour tracking mode for bass/diffuse
 regions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

trackIsoContour() follows constant energy level through STFT frames
instead of peaks. Useful for broad bass areas where peak detector finds
nothing. Preview in cyan, auto-detects spread on commit (naturally large).

Toggle: ≋ Contour button or C key. Mutually exclusive with ⊕ Explore.
