Release v0.3.0: five new components · organui/organui

Five new components. Nothing is breaking: upgrading from v0.2.0 only adds items.

bunx shadcn@4.22.1 add @organui/cell @organui/body-map @organui/dermatome-map @organui/image-viewer @organui/growth-chart

New components

Cell (docs): a 3D animal cell with a quarter cut away, 15 selectable structures and 4 named views. It's built on the organ viewer and works with the anatomy tree. The model is an original CC0 schematic.
Body map (docs): a front and back body outline for recording where something hurts. Regions are selectable by pointer or keyboard, and the value is a list of region IDs. Sides are the patient's.
Dermatome map (docs): the 28 ISNCSCI sensory levels (C2 to S4–5) on a front and back body map, with key sensory points. It's a simplified illustration, not a clinical tool.
Medical image viewer (docs): a CT/MRI slice viewer with window/level presets, zoom, pan and pixel values. It installs lib/dicom.ts, a reader for uncompressed single-frame grayscale DICOM, and lib/head-phantom.ts, a synthetic head phantom to use as sample data.
Growth chart (docs): percentile curves and z-scores for weight, length/height and head circumference. It ships no growth data. You pass the reference tables yourself. WHO's tables need WHO's permission for commercial use (in WHO's anthro package they're GPL-3), so the docs explain where to get WHO or CDC tables and under what terms.

The organ viewer, molecule viewer, DNA helix and image viewer now say in their install message that they need one of shadcn's Base UI styles, such as base-nova. On a Radix style, their toolbar buttons silently do nothing.
Registry items require cn@^0.5.0, and a test keeps item dependency ranges in step with the versions the registry is tested against.
