Add docs recipe for raw() and explain() query debugging #5

Background

QueryBuilder exposes raw() and explain() to inspect the compiled APICalypse body. This is helpful when users are learning how typed builder calls map to IGDB syntax.

Proposed change

Add a compact recipe that builds a typed query, shows the expected compiled output, and explains when to use raw() versus explain().

Acceptance criteria

• Uses supported builder methods such as .select(), .where(), .sort(), and .limit().
• Shows the generated APICalypse body in a code block.
• Mentions that explain() logs and returns the builder for continued chaining.
• Does not add runtime behavior.

Files likely involved

• docs/querying.md
• docs/examples.md
• src/query/QueryBuilder.ts
