docs(mcp): regenerate mcp-tools diagram for 43 tools (+ notion); fix count in CLAUDE.md

release/v3.8.8 added notionTools.ts (6 tools) → MCP total is 43, not 37, but the
diagram asset (mcp-tools-43.svg) was never generated and MCP-SERVER.md/CLAUDE.md
still said 37. Create mcp-tools-43.{mmd,svg} (rendered via mermaid-cli), repoint
MCP-SERVER.md + docs/diagrams/README.md, update CLAUDE.md count to 43, and remove
the superseded mcp-tools-37 source/asset.

Note: full 'next build' OOM'd locally (session cgroup limit); the SVG ref resolves
(file present at path) and check:docs-sync passes — CI runs the authoritative build.
