Pull Request Overview

This PR standardizes the test command to run in non-watch mode by default. The change ensures that pnpm test consistently executes tests once and exits, which is appropriate for both local development and CI environments.

Key Changes:

• Modified the test script to use vitest run instead of vitest (watch mode)
• Simplified the CI workflow to use pnpm test directly instead of passing --run flag
