Release Simple DB 0.1.2 with lower Results grid

[suzdalenko-dev]

What changed

• Release Simple DB 0.1.2.
• Move query results into a resizable Simple DB Results view in VS Code's lower Panel so the SQL editor stays visible above.
• Render SELECT output as a SQL Developer-style grid with row numbers, sticky headers, scrolling, pagination, multiple result-set tabs, copy actions, and CSV/JSON/XLSX export.
• Fix the webview JavaScript escaping bug that could leave successful SELECT queries stuck on Loading results….
• Keep non-query execution messages and affected-row information in the same lower Results view.
• Add a concise English Quick start and change the last Spanish truncation message to English.
• Add regression coverage that executes the generated Results script, feeds it SELECT metadata plus a returned row, and verifies the row is rendered in the grid.

Why

A SELECT could execute successfully and appear in History with returned rows while the previous Results webview remained on Loading results…. The result UI also opened as an editor-side webview instead of the database-client layout requested for Simple DB.
