CLI-native knowledge graph toolkit for SysML v2. Single binary, dual
mode (CLI + MCP server). Built on tree-sitter-sysml for parsing,
inspired by GitLab's Global Knowledge Graph architecture.

Workspace crates:
  - nomograph-core: Generic traits (Graph, Index, Parser, Scorer)
  - sysml-core: SysML v2 domain (walker, graph, vocabulary, render)
  - sysml-cli: CLI (clap) and MCP server (rmcp, feature-gated)

Commands:
  parse, validate, index, search, inspect, trace, check, query,
  render, stat, plan, diff, scaffold, skill

Highlights:
  - 116 tests passing
  - JSON output on all commands
  - Template-based rendering (traceability matrix, requirements table)
  - Structural + metamodel completeness checks
  - Model diff for CI/CD merge request gates
  - GitLab CI templates included (ci/)

Install:
  cargo install sysml-cli
  cargo install sysml-cli --features mcp
