Release Simple DB 0.1.6 — Full SQL editor context menu

[suzdalenko-dev]

Summary

Release Simple DB 0.1.6 with the complete SQL-editor right-click workflow requested for daily database work.

What changed

• Expands Simple DB > in any SQL editor with configuration and connection operations.
• Adds connection selection/creation plus Connect, Disconnect, Test Connection, Open Connection JSON, Set Password, Delete Connection, and New Query actions that work from the SQL file context.
• Keeps query execution and transaction actions in the SQL context menu.
• Keeps Go to Definition and Go to Declaration and adds explicit Oracle Go to Package Specification and Go to Package Body actions.
• Preserves the 0.1.5 rule that the Command Palette exposes only Simple DB: Open Configuration.
• Connection-oriented commands invoked from a SQL file resolve the connection attached to that file, or prompt for one when needed.
• Updates release documentation and package version to 0.1.6.

Why

The 0.1.5 SQL right-click submenu did not expose the complete connection/query/navigation workflow. Users still had to leave the SQL editor for important database actions, and Oracle package specification/body navigation was not explicit.

Validation

• 76/76 automated tests passed locally.
• ESLint passed.
• Real SQLite navigation smoke test passed.
• npm audit --omit=dev: 0 vulnerabilities.
• VSIX 0.1.6 built and its package contents were verified.
• Published branch is exactly 1 commit ahead and 0 behind main.
