🔴 jsonb[] field type has no coercion handler in csv-to-pg parser, producing corrupted SQL output

The PR adds jsonb[] as a valid FieldType and uses it for secure_table_provision.fields and secure_table_provision.grant_privileges, but the downstream csv-to-pg parser (packages/csv-to-pg/src/parse.ts:461-472) has no 'jsonb[]' case in its getCoercionFunc switch statement. This causes jsonb[] values to fall through to the default handler, which calls String(value) on the raw value. Since node-postgres returns jsonb[] columns as JavaScript arrays of parsed objects, String([{"a":1},{"b":2}]) produces "[object Object],[object Object]" — corrupted, unrecoverable data in the generated SQL INSERT statements.

Prompt for agents 
The csv-to-pg parser at packages/csv-to-pg/src/parse.ts needs a new case for 'jsonb[]' in the getCoercionFunc function (around line 460, before the default case). The handler should:
1. Get the rawValue from the record
2. Check for null tokens
3. Verify the value is an array
4. JSON.stringify each element of the array
5. Format as a PostgreSQL array literal string, e.g. using the psqlArray helper but with JSON-stringified elements, or a custom approach like: '{' + array.map(el => '"' + JSON.stringify(el).replace(/\\/g, '\\\\').replace(/"/g, '\\"') + '"').join(',') + '}'
6. Return it as a string constant node

Example case to add in packages/csv-to-pg/src/parse.ts after the 'jsonb' case (around line 460):

    case 'jsonb[]':
      return (record) => {
        const rawValue = record[from[0]];
        if (isNullToken(rawValue)) {
          return makeNullOrThrow(fieldName, rawValue, type, required, 'value is empty or null');
        }
        if (Array.isArray(rawValue)) {
          if (rawValue.length === 0) {
            return makeNullOrThrow(fieldName, rawValue, type, required, 'array is empty');
          }
          const elements = rawValue.map(el => JSON.stringify(el));
          const arrayLiteral = psqlArray(elements);
          if (isEmpty(arrayLiteral)) {
            return makeNullOrThrow(fieldName, rawValue, type, required, 'failed to format array');
          }
          const val = nodes.aConst({ sval: ast.string({ sval: String(arrayLiteral) }) });
          return wrapValue(val, opts);
        }
        return makeNullOrThrow(fieldName, rawValue, type, required, 'value is not an array');
      };
