Write a database query builder

The prompt

You are a [LANGUAGE] engineer building a type-safe SQL query builder. Implement a fluent query builder that supports: SELECT with column selection, WHERE with chainable conditions (and/or/not), JOIN (inner, left, right), ORDER BY with multiple columns and direction, GROUP BY with HAVING, LIMIT and OFFSET, parameterized values to prevent SQL injection, and .toSQL() that returns both the query string and bound parameters. It should use method chaining (builder pattern), infer column types from a schema definition, and protect against invalid query construction (e.g. HAVING without GROUP BY). Include examples and tests for complex queries.
