name: 'Build shaft-mcp Live Launcher Jar'
description: >-
  Sets up JDK 25, builds a runnable shaft-mcp jar plus its runtime
  dependencies, and writes a `java @argsfile` launcher for it (same recipe as
  guided-workflows-live.yml, with -DheadlessExecution=true added to the
  argsfile so the spawned MCP server process runs headless -- Web.java's
  "system:properties" @Sources entry wins inside that process). Exports
  MCP_JAVA (java executable) and MCP_ARGS (path to the argsfile) as job
  environment variables so callers pass
  "-D<gate>.liveMcpCommand=${MCP_JAVA} @${MCP_ARGS}" to a live test run.
  Callers needing other reactor modules built (e.g. shaft-cli) must install
  them separately -- this action only builds shaft-mcp.
