docs(bench): nine-server public AutoCAD MCP leaderboard as the README hero visual

source_review.json extended with three projects reviewed 2026-07-23 (LokmenoWer/best-cad-mcp B/74, daobataotie/CAD-MCP B/35, zh19980811/Easy-MCP-AutoCad C/30) and our entry updated to the released v1.4.0 (95: CI matrix, PyPI packaging, A/B gate, paper space, ISO 286, opt-in solids). Chart regenerated via render_chart; README benchmark section now opens with the leaderboard + 9-row table, source-review lane merged into it.

+Fixed public 100-point rubric — CAD breadth (25), correctness and delivery
+(20), backends/platforms (15), engineering production (15), tests and
+maintenance (15), security and operations (10) — applied to the public source
+and documentation of each project
+([`benchmarks/source_review.json`](benchmarks/source_review.json), dated).
+Stars and raw tool counts score nothing. Evidence grade **A** = source plus
+locally executed evidence, **B** = deep source review without a full live run,
+**C** = documented tool surface only. This is a source review, not a shared
+live run — the lanes below are the runtime evidence.
