Detailed Description

Discrete taper (window) coefficient generation and in-place application for MayaFlux::Kinesis.

Pure numerical functions producing taper coefficient vectors and applying them in-place to contiguous double-precision spans. No MayaFlux type dependencies. Domain-agnostic.

Two usage patterns are supported:

1. Generate then apply separately: auto t = Kinesis::Discrete::hann(n); Kinesis::Discrete::apply_taper(signal, t);
2. Apply directly without materialising coefficients: Kinesis::Discrete::apply_hann(signal);

All generation functions return a vector of length n. The single-sample edge case always returns { 1.0 }.

SIMD notes: apply_taper and apply_rectangular are auto-vectorisable under -O2 -march=native. Generation functions invoke std::cos and are scalar.
