#!/usr/bin/env bash
# Stops the Vectis backend (FastAPI/uvicorn, port 8000) and frontend (Vite,
# port 5173) dev servers started by start.sh.
#
# start.sh doesn't write a PID file (it just backgrounds two child processes
# and traps EXIT/INT/TERM to kill them) so if that terminal was closed
# instead of Ctrl-C'd, or the script was backgrounded/disowned, the servers
# can be left running as orphans. This finds them by the port they're
# listening on (falling back to a command-name match) and kills them
# directly, which works regardless of how start.sh exited.
