Lists WordPress posts, pages and products with pagination support. Use ONLY when the user explicitly asks to list, browse, search, or reference existing site content by `id` (e.g. "find the About page", "list my products"). Do NOT call this as a default discovery step — on large sites the response is context-heavy. Returns items the current user is allowed to read (published for everyone; drafts, pending, private, and scheduled items are included only when the user has permission to see them). Each item exposes its `status` so you can distinguish drafts from live content. Default returns 10 items sorted by most recently created. Use `search` to filter by keywords in title or content. Use `post_type` (`all`, `post`, `page`, or `product`) to narrow results; `product` requires WooCommerce (or another plugin that registers the `product` post type).
