hermes - 💡(How to fix) Fix [workflow-engine] HIGH: README documents config env vars the engine never reads

Severity: HIGH (docs/config divergence)

README documents config env vars the engine never reads, and the real DB path is hardcoded to a different location than documented.

Evidence

• README "Config" table documents WORKFLOW_DB_PATH, WORKFLOW_DEFAULTS_DIR, WORKFLOW_YAML_DIR, WORKFLOW_POLL_INTERVAL, TOOL_CATALOG_ROOT. Grep proves none are read in engine/, daemon.py, or _shared.py.
• plugins/workflow-engine/engine/wiring.py:25 hardcodes ~/.hermes/switchui-workflows.db — a different filename than the README's documented path.

Upstream convention violated

Rubric #4 (config precedence chain, no env-only / no phantom config) and #11 (docs accuracy). Upstream plugins (honcho) resolve config through a documented precedence chain and the documented keys are actually read.

Fix

Either wire the documented env vars in create_engine/CronPoller/path resolution, or delete the false rows from the README and document the real hardcoded path. Prefer wiring at least WORKFLOW_DB_PATH.
