ggcolonviz 0.0.6

• Improved robustness of internal stat layers when handling unknown or missing input parts.

ggcolonviz 0.0.4

• Added a Basics vignette walking through the core plotting workflow.
• Expanded the test suite to cover blueprint geometry, sf helpers, stat layers, and the variant registry.

ggcolonviz 0.0.2

• Initial release.
• geom_colon() and geom_colon_label() for visualizing the colon with ggplot2.
• Blueprint system for configurable colon anatomical layouts, with "standard" and "sescd" variants shipped.
