RubyLLM bundles a static models.json that doesn't know about models
released after the gem was published. Self-hosted users configuring
newer models hit ModelNotFoundError.
Added a rake task that refreshes the registry from models.dev and saves
to disk. ~~Called during Docker image build so every deploy gets fresh
model data. Falls back silently to the bundled registry if models.dev is
unreachable.~~
Commit the models.json file to code so it is available across
deployments.
