Add Airport Lounge List to Websites

[jackculpan]

Adds Airport Lounge List to the Websites section.

It is a production airport lounge directory. Every page registers imperative navigator.modelContext tools:

• get_current_page — read the current page as Markdown
• search_lounges — search the directory by name, airport, city, country or IATA code
• get_airport_lounges — list an airport's lounges by IATA code
• get_lounge_details — look up one lounge by slug
• navigate_to — move to another page on the site

Each tool reads the Markdown twin the page already serves, so the agent and the human see the same content. Tools re-register on Turbo navigation and unregister through an AbortSignal.

Kept alphabetical within the section.

Do you have a page on the site that talks about the WebMCP support, introduce the tools etc.? It'd be good to link to that instead.
