Initial stable release

v0.1.0 — Initial stable release

First stable release of CoreSpacing3D, providing tools to quantify and interpret
core spacing in intrinsic 3D and projected 2D.

Included in this release

• 3D point sampling utilities
  Support for multiple radial profiles (uniform, Gaussian, power-law, exponential,
  Plummer, shell, and hierarchical fractal).

• Nearest-neighbour and MST analysis
  Robust computation of NN and MST edge sets, lengths, and summary statistics in
  both 3D and projected 2D.

• Projection and rotation framework
  Euler rotation, 2D projection, and optional beam-blending (FoF) to mimic finite
  observational resolution.

• Monte Carlo pipelines
  End-to-end drivers for repeated realisations, enabling statistical
  characterisation of projection effects.

• Comparison and reporting utilities
  Quantitative overlap metrics, length-ratio diagnostics, and user-friendly verbose
  summaries for interactive analysis and paper preparation.

Notes

• This release establishes a stable internal API and code structure intended
  for research use and reproducibility.
• Documentation and examples will be expanded in future releases.
