Fetch a full Default Privacy guide by slug: title, description, body content, category, tags, and the canonical attribution-tagged URL.
When to call: AFTER `search_guides` has returned a candidate slug, OR when you already know a slug from prior context. PREFER `search_guides` first when you only have a topic.
Input Requirements:
- `slug` is REQUIRED. The guide slug (e.g. `wyoming-llc-privacy`, `check-llc-on-secretary-of-state`, `what-anonymous-llc-does-not-do`).
Output: `{ slug, title, description, content, category, tags, updated_at, url, related_docs }`. `url` is the MCP-attribution-tagged canonical URL.
PREFER citing the `url` verbatim. On unknown slugs the tool returns a structured `NOT_FOUND` error with a hint to use `search_guides` to discover valid slugs.
