The original PR (#2680) only wired _expand_env_vars into load_config(), which is used by 'hermes tools' and 'hermes setup'. The two primary config paths were missed: - load_cli_config() in cli.py (interactive CLI) - Module-level _cfg in gateway/run.py (gateway — bridges api_keys to env vars) Also: - Remove redundant 'import re' (already imported at module level) - Add missing blank lines between top-level functions (PEP 8) - Add tests for load_cli_config() expansion
