v0.2.0

Highlights

• Add an optional agent-facing runtime with init_kb, check_kb, get_context, and validate_kb
• Add a minimal MCP adapter that exposes the runtime through a small stdio JSON-RPC / MCP surface
• Add automated runtime and MCP adapter test coverage plus a minimal GitHub Actions CI workflow
• Refresh English and Chinese README onboarding, bootstrap guidance, and end-to-end validation docs for the v0.2.0 baseline
• Refresh example-kb maintenance metadata so the shipped health check fixture passes cleanly
