Adds Vertex AI as a first-class provider for Gemini models via Vertex's OpenAI-compatible endpoint. Vertex authenticates with short-lived OAuth2 access tokens (service-account JSON or ADC), not a static API key — the missing piece behind the recurring requests (#13484, #12639, #56259). - agent/vertex_adapter.py: OAuth2 token minting + refresh-on-expiry (5-min margin), ADC->service-account fallback, global vs regional endpoint URLs. Config precedence: env var > config.yaml > default. - plugins/model-providers/vertex/: provider profile (auth_type=vertex), reuses Gemini's extra_body.google.thinking_config translation. - runtime_provider: vertex short-circuit BEFORE the credential pool so a credentials-file path is never mistaken for a static API key; mints a fresh token + computes base_url per resolve. - run_agent + conversation_loop: _try_refresh_vertex_client_credentials() re-mints the token and rebuilds the client on a mid-session 401, so a long-lived gateway agent survives token expiry (~1h). - auxiliary_client: vertex auth_type branch for side-LLM tasks. - config.yaml: vertex.project_id / vertex.region (non-secret, bridged to env); credential path stays in .env (VERTEX_CREDENTIALS_PATH). - setup wizard + model picker: dedicated _model_flow_vertex; curated google/gemini-* model list; --provider choices. - pricing/metadata: Vertex prices off the gemini docs snapshot; endpoint host auto-maps to the vertex provider (no probe spam). - lazy_deps + pyproject [vertex] extra: google-auth, opt-in only. - docs: guides/google-vertex.md + providers page; tests for adapter + runtime resolution. Salvages and modernizes #8427 by @slawt onto current main: rewired from the legacy PROVIDER_REGISTRY path to the provider-profile architecture, moved non-secret config out of .env into config.yaml, and added the per-turn 401 token-refresh the original lacked.
