Compares versions per semver.org's real precedence rules, not naive string comparison — 1.10.0 correctly sorts after 1.9.0, and prerelease versions (1.0.0-alpha, 1.0.0-rc.1, ...) are ordered correctly too. Runs entirely in your browser.

Sort returns {"sorted": [...]}. Returns {"error": "..."} on a malformed version.
