OpenCode Fixes Azure Auth, Adds Qwen3.8 Flash

This is a small but high-leverage update: it smooths enterprise Azure workflows while making OpenCode Go more compelling for cost-conscious developers.

• –Azure users can authenticate through the CLI without switching runtimes or managing a separate API key.
• –The fix benefits Microsoft Entra ID workflows involving sign-in, resource selection, token retrieval, and deployment discovery.
• –Qwen3.8 Flash expands Go’s curated set of affordable models for agentic coding.
• –OpenCode’s model-agnostic architecture makes switching between providers and model tiers straightforward.
• –Developers already using Azure or OpenCode Go have a strong reason to upgrade immediately.
