test: add bash MCP server to integration test suite
Add mcp-bash server to both functional and performance integration tests. The bash server demonstrates excellent performance with 10 tools, 3 resources, and sub-millisecond startup time (972.799µs). 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
