feat: add Claude Opus 4.6 model support (#9119)

* feat: add Claude Opus 4.6 model support with 1M context window

Adds support for Claude Opus 4.6, Anthropic's latest model with:
- 200K base context window with optional 1M context variant
- Tiered pricing for >200K context (2x input/output pricing)
- Extended thinking/reasoning support
- Prompt caching support

Changes:
- Added model definitions for Anthropic, Bedrock, and Vertex providers
- Added OpenRouter 1M variant support
- Updated thinking models lists across all provider UIs
- Added context window switcher for Opus 4.6
- Updated JP cross-region inference models list

* feat: update featured model to Opus 4.6 in model picker

* chore: add changeset for Claude Opus 4.6

* fix: correct Opus 4.6 model IDs (no date suffix)
