Code Review

This pull request introduces a comprehensive testing, CI/CD, and code quality infrastructure to the project. This is a significant and high-quality contribution that greatly improves the project's maintainability, reliability, and developer experience.

The changes include:

• Testing: A robust testing foundation with Vitest, including unit tests for components and hooks, and end-to-end tests for key user flows like connection and querying. The use of mock infrastructure for Tauri is well-implemented.
• CI/CD & Automation: Configuration for GitHub Actions (as per the description), Dependabot, and Husky pre-commit hooks to automate testing, dependency updates, and code quality checks.
• Code Quality: ESLint and Prettier are set up with sensible configurations to enforce a consistent code style and catch potential issues early.
• Refactoring: Unused dependencies have been removed, and the README.md has been streamlined for clarity.

The overall implementation is excellent. I have only one minor suggestion regarding a placeholder URL in the README.md. Great work on this foundational improvement!
