The registry shows a version's changelog as one paragraph, without Markdown
or line breaks: a shared script turns the CHANGELOG.md section into
'Added: ...; ... Fixed: ...' for both the publish and the update workflows.
The publish workflow passes the version's CHANGELOG.md section to comfy-cli
(COMFY_NODE_CHANGELOG), icon.png is re-rendered from icon.svg at 512x512
with all four corners rounded, and the description covers the features.
