Add webmcpify to Libraries & Tools in AWESOME_WEBMCP.md

[TueJon]

Adds webmcpify to the Libraries & Tools section.

webmcpify is an MIT-licensed agent skill that integrates WebMCP into an existing web application end to end: it inventories the app, proposes a tool manifest for human approval, integrates the tools against document.modelContext, then verifies each tool by executing it in a real browser and heals failures. It follows the tool-design patterns from this repo's demos and treats the WebMCP guides in GoogleChrome/modern-web-guidance as the source of current best practices.
