fix(mcp): add auto-install to Playwright MCP wrapper

[atxtechbro]

Overview

This PR enhances the Playwright MCP wrapper script to automatically install the Playwright MCP server if it's not already installed. This follows the Spilled Coffee Principle by ensuring that the system can recover automatically without manual intervention.

Changes

• Update wrapper script to detect if playwright-mcp is installed
• Automatically run the setup script if the command is not found
• Add proper error handling and logging during the installation process
• Ensure the setup script is executable before running it

Motivation

The previous implementation required manual execution of the setup script, which violates the Spilled Coffee Principle. This change ensures that anyone can use the Playwright MCP server without having to manually run setup scripts.

Testing

• Tested by verifying that the wrapper script correctly detects when playwright-mcp is not installed
• Confirmed that the automatic installation process works correctly

Principles Applied

• Spilled Coffee Principle: Anyone should be able to destroy their machine and be fully operational again that afternoon
• Systems Stewardship: Maintaining and improving systems through consistent patterns
