Follow the same convention as the static module: remove local config.ini
fallback and --config/-i command-line argument entirely. All configuration
is now managed exclusively through confs service.
- Delete gateway/example.ini (moved to confs/configs/gateway.ini).
- Remove -i/--input option from boost::program_options; help (-h) and
version (-v) are the only CLI flags remaining.
- Simplify main.cpp config loading: remove local-file branch, always fetch
gateway.ini from confs with retry_on_refused=true waiting for confs ready.
- Update _run.sh: no longer passes any arguments; config comes from confs.
- Update README: remove example.ini references, -i flag docs, local file
mode description, and example.ini from directory structure tree.
- Clarify changelog entry for v0.7.0.
