fix: surface statement-level query errors and fix debug-mode crash

[MagnunAVFAzion]

What

Hardens error handling in the SQL package's postQueryDatabase:

1. Fixes a crash in debug mode. When the SQL API returned a per-statement
   result array containing a null entry (e.g. [{ error: 'no such table: ...' }, null]),
   the debug .map() accessed .results on null and threw
   Cannot read properties of null (reading 'results').

2. Surfaces statement-level errors. The API reports per-statement failures
   inside the data array rather than in top-level result.errors. These are
   now detected and returned as a proper error object, instead of being buried
   in the response data.

3. Updates docs to make the "check error before data" behavior explicit.

Problem Reproduction

Running a query (in localhost - nodejs server) against a non-existent table with debug true produced:

[TypeError: Cannot read properties of null (reading 'results')]

instead of a clean error response.
