Fabio LussiandClaude Opus 5.5 81ec430341 fix(meter): keep K-weighting stable below ~3.4 kHz sample rates
The shelf corner (~1682 Hz) sits at or above Nyquist for rates under
~3.4 kHz. The bilinear prewarp tan() then wraps negative (unstable
poles, +750 LUFS readings, -144 integrated) or aliases. Hold the
design frequency below Nyquist (0.49 * sr, as Coeffs::design does).
Coefficients at 8 kHz and above are unchanged.

Fixes #240
