A fresh root install on Linux (e.g. a new Proxmox/Ubuntu VM) places the Hermes
Agent at /usr/local/lib/hermes-agent and links the CLI into /usr/local/bin,
while the modern `hermes` launcher is a `#!/usr/bin/env bash` wrapper that
exec's the venv entrypoint. The old discovery only checked
~/.hermes/hermes-agent-style paths and parsed the launcher's shebang as a Python
interpreter, so on a root VM discover_agent_dir() returned None, bootstrap built
a WebUI-only .venv, and chat aborted at launch with "Python environment cannot
import both WebUI dependencies and Hermes Agent."
Two complementary fixes:
- Add /usr/local/lib/hermes-agent to discover_agent_dir()'s candidate list.
- Harden _agent_dir_from_hermes_cli() to follow the launcher's exec target (any
absolute path quoted in the wrapper) up to run_agent.py, not just a Python
shebang. Skips /usr/bin/env indirection.
Now `python3 bootstrap.py` works out of the box for root/container installs with
no HERMES_WEBUI_PYTHON override needed. Adds tests for the bash-wrapper shape,
the env-indirection no-false-positive case, and the FHS candidate probe; updates
docs/troubleshooting.md.
