docs(test-harness): comprehensive documentation update based on server reality testing
- Update CLI reference with actual commands (run vs test, missing commands) - Fix configuration reference to match real YAML structure from working examples - Add verified working examples (filesystem 8/8, everything 8/8 tests passing) - Update quick start guide with real commands and working examples - Correct protocol version references from 2024-11-05 to 2025-06-18 - Update main index with accurate feature descriptions and proven performance - Add server-reality examples that only test capabilities servers actually support - Include performance data from real test runs (0ms to 10+ seconds measured) - Document correct tool names, output formats, and error codes from actual testing - Add troubleshooting based on real issues encountered during verification This addresses the gap between documentation-driven and server-reality testing, ensuring all examples work with actual MCP server implementations. Working examples tested: - Filesystem server: 100% success rate (2.3s duration) - Everything server: 100% success rate (10.02s duration) Based on thorough testing with @modelcontextprotocol/server-filesystem and @modelcontextprotocol/server-everything to ensure documentation accuracy.
