+.SYNOPSIS
+    Manage the langgraph dev server on Windows.
+.DESCRIPTION
+    Start, stop, or check the status of the langgraph dev server.
+    The server starts from the skill root (where langgraph.json lives) so the
+    graph module is discovered correctly.
+.PARAMETER Command
+    start | stop | status
+.EXAMPLE
+    manage_dev_server.ps1 start    # idempotent — safe to call if already running
+    manage_dev_server.ps1 stop     # call once workflow returns {"status":"done"}
+    manage_dev_server.ps1 status   # print running/stopped + Studio URL
+#>
+param([string]$Command = "status")
