Why

The VitePress documentation (docs/) still describes the plugin as an OpenAPI/Swagger tool, with outdated taglines, feature descriptions, and an API Reference link pointing to a removed endpoint list. Since v0.2.0, the plugin renders OpenSpec project documentation — not OpenAPI specs. Visitors to the site will be confused about what the plugin actually does.

What Changes

• Rewrite docs/index.md hero section: update tagline, text, and feature cards to describe OpenSpec rendering
• Replace the "API Reference" action link with a link to the generated OpenSpec docs section
• Update feature descriptions: folder reader, change pages, specs index, sidebar/nav helpers — all OpenSpec concepts
