Release Simple DB 0.1.5 — SQL editor UX

[suzdalenko-dev]

What changed

• exposes only Simple DB: Open Configuration in the Command Palette; it opens the same Activity Bar container as the Simple DB icon
• keeps SQL-file actions in the Simple DB editor context submenu: configuration, connection selection, statement/script execution, and definition/declaration navigation
• makes connection and quick-input flows cancellable with Cancel / Close, Esc, or clicking outside
• stops reopening the SQL-file connection picker when nested connection creation is cancelled
• bumps the extension to 0.1.5 and updates the English README/changelog

Why

The 0.1.4 Command Palette still exposed several internal/daily commands, while the intended UX is one global entry point plus a SQL-file-specific right-click workflow. The nested connection picker also retained focus and reopened after cancelling connection creation, which made the flow feel impossible to close.
