Port of Zoo-Code PR #555. Registers `claude-fable-5` across the Anthropic,
Bedrock, Vertex, OpenRouter, Requesty and Vercel AI Gateway providers
(context 1M, direct maxTokens 128k / 8k on Bedrock+Vertex, adaptive-binary
reasoning, temperature unsupported), and routes the model through adaptive
thinking.
Fork-specific: our Vertex handler never received the adaptive-binary reasoning
routing that Zoo already had, so it emitted `{type:"enabled",budget_tokens}` for
Opus 4.7/4.8 and Fable 5. Recompute `thinking` via getAnthropicProviderReasoning
in AnthropicVertexHandler.getModel so Vertex matches the direct provider.
