v0.3.0 - True Wrapper Architecture

🚀 Major Release: True Wrapper Architecture

Complete architectural rewrite that spawns child MCP processes for true session isolation.

✨ Highlights

• 65% code reduction: 2,302 → 799 lines
• True isolation: Each session runs in its own OS process
• Dynamic tools: Tools fetched from backend at runtime
• 87.3% test coverage: 75 tests

🔧 Architecture Changes

• Wrapper spawns @playwright/mcp child processes
• JSON-RPC over stdio communication
• Automatic tool registration with sessionId parameter injection

🔒 Security & Stability

• Command injection prevention (npm package name validation)
• Race condition fixes (MAX_SESSIONS check, pendingRequests handling)
• Resource leak fix (stdin properly closed)

📦 Installation
