pub fn discover_config_path(dir: &Path) -> Option<PathBuf>Expand description
Probe dir for faucet.yaml, faucet.yml, then faucet.json. Returns the
first match in priority order, or None. When more than one candidate is
present, emits a tracing::warn! naming the runner-ups so a stale
faucet.yml next to the canonical faucet.yaml doesn’t go unnoticed.
