Changed
Default Sonnet model bumped to 5 across all providers following Anthropic's release.

claude-sonnet-5 - Azure Foundry:
claude-sonnet-5(default deployment name) - Vercel AI Gateway / OpenRouter:

Overridable per provider via CLAUDE_MODEL_SONNET_{AWS,VERTEX,ANTHROPIC,AZURE,VERCEL} and ROUTER_MODEL_MID. Docs (README, docs/PROVIDERS.md, secrets.example.sh, airun-docs) updated to reference Sonnet 5.
