Summary

Fixes the Copilot SQL runner tool when executing successful SQL statements that do not return a result set, such as CREATE TABLE, DROP TABLE, or CREATE ALIAS.

Previously, JobManager.runSQL() could return undefined. The tool passed JSON.stringify(undefined) into LanguageModelTextPart, which also evaluates to undefined and caused VS Code to throw an error when reading .length.

The tool now always returns a consistent JSON payload:

• Statements without a result set: {"success":true,"hasResultSet":false,"rows":[]}
• Statements with a result set: {"success":true,"hasResultSet":true,"rows":[...]}

Tests

• Added regression tests for statements with and without result sets.
• Manually verified successful CREATE TABLE and DROP TABLE statements through Copilot Chat.
• npm test passes: 186 tests.
• npm run typings passes.

Fixes #562

@Balrocj coul dyou please upload vsix?

[Balrocj]

@buzzia2001 I built the VSIX from this branch and attached it here for testing.

It includes the fix for SQL statements that complete successfully without returning a result set.

GitHub does not allow .vsix attachments, so the package is attached as a .zip.
