feat: add Claude Opus 4.6 support across all providers
Add Claude Opus 4.6 (claude-opus-4-6) model definitions and 1M context support across Anthropic, Bedrock, Vertex AI, OpenRouter, and Vercel AI Gateway providers. - Anthropic: 128K max output, /5 pricing, 1M context tiers - Bedrock: anthropic.claude-opus-4-6-v1:0 with 1M context + global inference - Vertex: claude-opus-4-6 with 1M context tiers - OpenRouter: prompt caching + reasoning budget sets - Vercel AI Gateway: Opus 4.5 and 4.6 added to capability sets - UI: 1M context checkbox for Opus 4.6 on all providers - i18n: Updated 1M context descriptions across 18 locales Also adds Opus 4.5 to Vercel AI Gateway (previously missing) and OpenRouter maxTokens overrides for Opus 4.5/4.6. Closes #11223
