Rebrand in response to a trademark report regarding the DEEPL mark.
Renames the Go module path, exported symbols, binary, systemd/launchd
services, Docker images, and CI artifacts; adds a trademark disclaimer
to the README and removes screenshots containing DeepL branding.
BREAKING CHANGE: Go module path is now github.com/OwO-Network/DLX.
translate.TranslateByDeepLX is now translate.TranslateByDLX and
DeepLXTranslationResult is now DLXTranslationResult. The release
binaries, systemd service, and Docker images are renamed from
deeplx to dlx.
install.sh always downloaded the linux_amd64 binary, so arm64/386/mips machines got a binary that does not run. Detect the architecture via uname and pick the matching release artifact; releases already ship those builds.
