Plexus 0.2.0

Plexus 0.2.0 is a GitHub Release of the zero-dependency capability discovery and wiring mesh.

Source commit: $sha
Source tree: $tree

Highlights

• Graph export, pipeline-script generation, manifest export, and a zero-dependency MCP stdio server for discovery, wiring, planning, and routing.
• Hardened MCP stdio request errors from the latest main work: malformed requests and invalid params now return structured JSON-RPC errors without stopping the server.
• Discovery remains declared and receipt-backed: Plexus reads manifests and reports evidence boundaries rather than importing or running tools.
