Revision history for Math-SegmentedEnvelope

0.03  2026-09-23
    - High-performance C XS engine rewrite with fast segment caching
    - TinyExpr formula support with JIT compilation (x86-64 / TCC)
    - Constructors: adsr(), asr(), perc(), spline() (Catmull-Rom)
    - Transforms: scale, stretch, offset, invert, normalize, quantize, trim,
      lerp, resample, clamp, smooth, derivative, integrate, concat, blend,
      add, multiply, with_duration, clone, copy
    - Boundary modes: is_hold, is_fold_over, is_wrap_neg
    - Scalar definite integral via area() / integral()
    - Operator overloading: callable envelopes ($e->($t)), arithmetic (+, -, *, neg),
      and descriptive stringification
    - Storable support: safe freeze, thaw, and dclone
    - Comprehensive example suite (120 examples) covering audio synthesis & DSP,
      psychoacoustics, 3D raymarching, laser art, cymatics, physics, kinematics,
      robotics, aerospace, and multi-dimensional envelopes
