RTVC (CorentinJ's 50k-star SV2TTS repo) is archived; its users need a
maintained home. New docs/migration/real-time-voice-cloning.md maps
every RTVC concept to its OmniVoice equivalent (encoder+utterance →
reference clip, toolbox → app, vocoder choice → Settings → Engines,
demo_cli.py → REST API/CLI/MCP), is honest about what RTVC did that we
don't (research toolbox, three-stage training, MIT license, smaller
footprint), and walks the first clone with verified UI labels only.
Wired into docs/features.yaml's existence-checked docs list and linked
from the README Quickstart.
README tagline now states the local-first promise verbatim at the very
top: "No accounts. No API keys. No cloud." — everything else on the
front page is unchanged.
