fix: add run parameter to vitest command in rules (#5991)

When running vitest without the run parameter, it enters watch mode and waits for user input (like pressing q to quit), causing tests to hang in the terminal.

This change updates the documentation to specify using npx vitest run instead of just npx vitest to ensure tests run to completion without requiring user interaction.
