v0.5.2

Register the MCP server the awareness document tells agents to call.

\claude mcp list\ showed no jevqueue server. The plugin shipped \mcp/jevqueue_mcp.py\ and the awareness document told every agent to call \jevqueue_decide\ -- but no manifest declared the server, so the tool did not exist.

Claude Code, Codex and GitHub Copilot now declare it. \�in/jevqueue-mcp.mjs\ finds a Python interpreter (python3, python or py -3, whichever is actually there) and hands the process over with stdio inherited. Codex gets its own configuration file, because its legacy plugin parser does not expand placeholders in MCP arguments.
