Build a SQL query rewriter in the sandbox called sql_rewriter.py.

It reads one SQL SELECT statement from standard input and prints an
EQUIVALENT rewritten query to standard output. The rewritten query must return
the EXACT same result set as the original when executed against the same
database.

Your rewriter may normalize, transform, or restructure the query any way you
like (e.g. convert `WHERE x IN (1,2)` to `WHERE x = 1 OR x = 2`, or use a
different but equivalent JOIN form), as long as the results are identical.

The verifier runs both queries against a real SQLite database (the `sqlite3`
module is built into Python) and compares the result sets row-for-row,
including column order.

Test it against the verification oracle before replying DONE.
When the goal is met and verified, reply exactly: DONE.
