## What's New

### Remote Backup Improvements

- **SFTP**: Separated `start_client` / `auth` steps for cleaner authentication flow
- **SFTP**: Auto-save host keys to `known_hosts` on first connection
- **SFTP**: Support non-standard port host key lookup
- **SFTP**: New `allow_password_fallback` parameter to control private key auth fallback behavior
- **WebDAV**: Custom opener now properly handles PROPFIND redirects while preserving auth headers and request method

### Bug Fixes

- Fixed `webdav` / `cloud` upload where `uploaded_files` was not collected in `_upload_to_cloud()`
- Fixed `--debug` mode not taking effect due to missing `force=True` in `logging.basicConfig`

### Documentation

- README translated to 9 languages (EN/ZH/DE/ES/FR/JA/KO/PT/RU)
- All READMEs include shields.io badges and language switcher
- Updated command list to 37 commands
- Updated code structure to 37 modules

### Internationalization

- Completed translations for all 9 languages (665 keys each, 0 missing)
- Removed 4 obsolete `cmd.remote.*` keys from all locales

### CI/CD

- New CI workflow: pytest runs on push/PR to dev/main (3 platforms x 2 Python versions)
- Release workflow: binary filenames now include version, platform, and architecture
- Release workflow: reads `releases/v{version}.md` for GitHub Release description
- Nuitka build: added missing dependencies (paramiko, minio, reedsolo, watchdog)

### Testing

- 940 tests passed, 0 failed
- Fixed test state pollution: locale and logging level now properly restored in tearDown
