refactor(mcp): simplify Playwright MCP server configuration

[atxtechbro]

Overview

This PR simplifies the Playwright MCP server integration by using npx to directly execute the latest version of the package, eliminating the need for wrapper scripts, setup scripts, and manual installation.

Changes

• Replace wrapper script with direct npx command
• Use @microsoft/playwright-mcp@latest to always get the latest version
• Remove unnecessary setup and wrapper scripts
• Eliminate maintenance overhead

Motivation

The previous implementation was unnecessarily complex, requiring wrapper scripts and manual installation steps. This simpler approach:

1. Reduces maintenance burden - No need to update scripts when the package changes
2. Eliminates installation steps - npx handles everything automatically
3. Always uses the latest version - The @latest tag ensures we're always using the most recent release
4. Works immediately - No need to run setup scripts or install anything manually

Testing

• Verified that the MCP server loads correctly with this configuration
• Confirmed that the server works with both Amazon Q and Claude Code

Principles Applied

• Subtraction Creates Value: Removing unnecessary complexity creates a more maintainable solution
• Spilled Coffee Principle: The system works immediately without manual setup steps
