REM  nodeagent - PORTABLE launcher (no install, no admin, no scheduled task)
REM
REM  Purpose: bring the agent up for a quick test WITHOUT running install.cmd.
REM  The agent is zero-config: on first run it creates %USERPROFILE%\.nodeagent\
REM  (agent.json with a random PSK + self-signed cert) and starts listening.
REM
REM  Usage:
REM     run-portable.cmd        start in foreground (Ctrl+C to stop)
REM     run-portable.cmd start  same as above
REM     run-portable.cmd background start hidden, then print status
REM     run-portable.cmd stop   stop the background instance
REM     run-portable.cmd status show whether it is running
REM
REM  IMPORTANT: the agent takes NO command-line arguments (it does not parse
REM  argv at all). The listen port comes from %USERPROFILE%\.nodeagent\
REM  agent.json -- the "<port>" below is used ONLY by this script's own status
REM  check. To change the port, edit agent.json, not the command line.
REM
REM  Notes:
REM    * Pure ASCII on purpose (see install.cmd) so it survives the CMD code page.
REM    * No admin needed. Nothing is written outside this folder and %USERPROFILE%.
REM    * "background" still dies with the parent CMD window; use it for a test
REM      session, not as a permanent daemon. For that, run install.cmd once.
