Detailed Description

Authentic one-pole exponential IIR low-pass smoother.

Implements analog-style smoothing. Anti-denormal protected.

Internal state is double precision: in float the recursion stalls once coeff * delta rounds back to the same value, parking the output around ulp(target) / (1 - coeff) away from the target (about 1e-5 for a 10 ms tau at 48 kHz and unity-scale targets), outside the settle window, so isSmoothing() would never turn off. The public API stays float.
