feat(types): add claude-opus-4-8 to Anthropic, Bedrock, and Vertex registries

- Register claude-opus-4-8 in anthropicModels with 1M context, 128k output,
  supportsReasoningBudget, supportsReasoningBinary, supportsTemperature: false
  (mirrors 4.7 - no breaking API changes per the official migration guide).
- Register anthropic.claude-opus-4-8 in bedrockModels with cache points,
  cachableFields, and 1M context tier pricing.
- Register claude-opus-4-8 in vertexModels with the same shape.
- Add anthropic.claude-opus-4-8 to BEDROCK_1M_CONTEXT_MODEL_IDS and
  BEDROCK_GLOBAL_INFERENCE_MODEL_IDS.
- Add claude-opus-4-8 to VERTEX_1M_CONTEXT_MODEL_IDS.
