pub fn cli_flag_map() -> HashMap<String, String>Expand description
Map every settings leaf (dotted path) to its user-facing CLI flag(s).
Walks start’s flattened SettingsArgs via clap reflection so the
/settings UI doesn’t have to hand-maintain a parallel table that drifts
from the actual flags. Output format: "--registry-data-dir, -d" (long,
then short if any). Args whose id doesn’t follow the <prefix>-<field>
convention (e.g. the top-level --config flag, clap’s built-in --help)
are skipped, they don’t correspond to a settings leaf.
