[VIP] WP Menu Nav Cache (v2)

Function-based wp_nav_menu() output caching plugin for WordPress/VIP-style environments.

Core behavior

• Caches menu HTML via pre_wp_nav_menu + wp_nav_menu hooks.
• Uses generation-based invalidation (wpvip_nav_menu_generation) in object cache group wpvip_nav_menu.
• Defaults to a 1-hour cache TTL (HOUR_IN_SECONDS), filterable with wpvip_nav_menu_cache_ttl.
• Ships the wpvip_nav_menu_should_cache filter and default callback that disables cache for logged-in users and singular pages.

Additional salvage from Automattic/cache-nav-menus

• Adds parse_query hook to force cache_results = true for nav_menu_item queries, reducing database pressure on cold paths.
