Add local Ollama as an AI Hub provider for claude-code

Ollama v0.14+ speaks the Anthropic Messages API natively, so the
registry drives it with a fixed 'ollama' token and runtime-listed
models: static_token skips secret storage everywhere keys resolve,
models_dynamic defers model validation to the live /api/tags list,
and the setup wizard installs the right GPU variant and starts the
service before listing local models. Doctor stops treating the
endpoint port as part of the hostname.
