* feat(nvidia): add NVIDIA provider with onboarding flow
Add the NVIDIA build.nvidia.com API as a bundled provider. Default model
is nvidia/nvidia/nemotron-3-super-120b-a12b: first segment is the provider
id, remaining "nvidia/nemotron-3-super-120b-a12b" is the literal upstream
model id (which happens to start with "nvidia/" because NVIDIA is also the
model maker).
Supporting core change: introduce a provider capability flag
nativeIdsIncludeProviderPrefix so providers whose native catalog ids
intentionally include their provider prefix (OpenRouter) opt into self-prefix
dedupe in modelKey, without hardcoding provider names in core. Providers
whose ids merely happen to start with their own name (NVIDIA) leave the flag
unset and get the full <provider>/<model-id> concatenation.
- extensions/nvidia/*: new plugin, catalog, onboarding, tests, docs
- extensions/openrouter/index.ts: declare nativeIdsIncludeProviderPrefix
- src/plugins/types.ts: add field to ProviderPlugin
- src/plugins/registry.ts: populate self-prefix set on registration
- src/agents/provider-self-prefix.ts: sync accessor used by modelKey
- src/agents/model-ref-shared.ts: modelKey consults the flag
- test updates for affected surfaces
