# Start/stop the mock inference server and point the app at it as a REAL
# configured provider.
#
# Why: the desktop app boots to the onboarding overlay when no provider is
# configured - a fullscreen div that intercepts every click, which killed
# the app-update legs. Seeding a fake key makes the overlay vanish but
# leaves a lying app; this makes the app GENUINELY configured (config.yaml
# provider + key env, exactly what tests-js/scripts/mock-server.ts's
# dev:mock flow writes) with a real, chat-capable backend.
#
# Usage (sourced from a driver):
#   mock_start <workroot>      start, write config into $HERMES_HOME
#   mock_stop                  kill the background server
#
# Requires: ASSETS (e2e-assets dir), LOG_DIR, HERMES_HOME, ok/fail helpers.
