ADK Rust Provider Selection

Overview

Map product constraints to provider choice, then verify env and feature wiring before implementation.

Workflow

1. Identify constraints: latency, cost, local/offline, tool-calling, streaming.
2. Pick provider and model family from the matrix.
3. Validate required env vars using scripts/provider_env_matrix.sh.
4. Confirm feature flags in Cargo manifests.

Guardrails

1. Do not assume API key names; verify exact env var keys.
2. Keep provider selection explicit in code and docs.
3. Include at least one provider-specific smoke command.
