0.15.0

Added

• prepare(source): pads icon-node labels narrower than h so Pele's layout box is as wide as the drawn icon. Without it, edge ends and arrowheads land under the icon. Use mount(el, prepare(src), { icons }).
• Website: an icon browser at /icons/ (search by name and tag, category chips, stroke-width slider, click to copy an @{ icon } snippet and the import line) and /icons.json ({ version, icons: [{ name, category, tags }] }) for agents.

Changed

• README: badges, links to the website and docs, a hero animation, generic comparison examples (client, API, auth server), and icon examples shown as source text because GitHub's Mermaid renderer cannot draw them.
