`hermes gateway install` generates a systemd unit that execs Python
directly, bypassing the Nix wrapper. The wrapper sets HERMES_BUNDLED_SKILLS,
HERMES_BUNDLED_PLUGINS, HERMES_WEB_DIST, HERMES_TUI_DIR, HERMES_PYTHON,
HERMES_NODE, LD_LIBRARY_PATH, and PYTHONPATH — all absent from the generated
unit. Result: the gateway service runs without skills, plugins, or native
libs, silently breaking platform adapters (discord, etc.) even when the
correct deps are installed.
Capture these env vars at `gateway install` time and persist them as
Environment= lines in the unit file. System-mode units remap paths from
the calling user's home to the target user's home.
