Running the server

tools/run_server.py runs OpenSim with no particular supervisor (all paths from the .env):

command	does
`python tools/run_server.py start`	start OpenSim in the background (pid in `bin/opensim.pid`)
`python tools/run_server.py stop`	clean shutdown through WorldBridge's console op when allowed (else `save_world`, then SIGTERM on Linux); forced (`taskkill /F /T`, SIGKILL) only if still running after the wait
`python tools/run_server.py supervise`	foreground: start, and start again whenever it exits (60 s backoff)
`python tools/run_server.py status`	running or not

OpenSim always starts headless with -console=rest (a detached process has no terminal, so a local console dies at startup); the REST console stays off while the .env leaves PARACOSM_CONSOLE_USER empty. OpenSim checks only the user name: with a user set and PARACOSM_CONSOLE_PASS empty, an empty password logs in, so set a strong one whenever you set the user. tools/region_restart.py deploys new DLLs across a restart: under a supervisor it lets the supervisor relaunch; with none it starts OpenSim itself.

Linux: paracosm.service here is a systemd unit (edit the paths and user; systemctl enable --now paracosm).
Windows: a Task Scheduler task "At startup", action python C:\path\to\paracosm\tools\run_server.py supervise, "Run whether user is logged on or not"; or any service wrapper (NSSM) around the same command.
