rename config window to settings and update CLI entry points

- Replace `--config`/`subminer config` (no action) with `--settings`/`subminer settings`
- `subminer config` now requires an explicit action (`path` or `show`)
- `--settings` previously opened Yomitan; replaced by `--yomitan`
- Linux tray update installs AppImage via electron-updater instead of manual flow
- macOS update dialog activation and curl-fetch routing fixes
- Delete stale compiled artifacts (main.js, app-updater.js)
