Pull request overview

Adds client-side handling for SQL Tools Service “formatting failed” notifications so users get an actionable parse-error warning (with feedback + suppression), while also clarifying formatter setting descriptions and bumping the bundled SQL Tools Service version.

Changes:

• Listen for textDocument/formattingFailed and show a parse-error warning with “Send Feedback” and “Don’t Show Again” actions, gated by a new setting.
• Add telemetry actions for parse-error notification interactions and a shared feedback URL constant.
• Improve formatter setting descriptions (Preview vs existing) and add/extend unit tests to validate the new behavior and configuration metadata.
