Two more spawns inherited the gateway's full environment. The bot
desktop launcher copied os.environ minus the display variables; the
agent drives that desktop and its dock opens xfce4-terminal, so every
provider key and bot token was one click away. The Telegram gmail-triage
buttons ran HERMES_HOME/scripts/gmail-triage/*.sh with no env at all, a
path the agent can write. The desktop now builds from
served_profile_child_env() like the agent browser (keeping the user's
HOME); the triage scripts use build_subprocess_env like cron and
webhook-filter scripts.
