pub fn init_config_table(conn: &Connection) -> Result<(), CliError>Expand description
Create the cli_config key-value side-table if it does not exist.
M2: CREATE TABLE IF NOT EXISTS makes this idempotent — safe to call on any vault (old, new,
or restored from snapshot). Called by Session::create; also called at the top of read_config
as a defensive ensure-table-then-read guard.
