Migrate prompts and code from Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5. Update model strings, remove unsupported beta headers, and optionally adjust prompts for behavioral changes.

• Migrate from Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5
• Update model strings based on platform

• Apply prompt adjustments only if user requests them

• Replace model strings per platform (API, Bedrock, Vertex, Azure)
• Remove unsupported beta headers with comment note
• Set effort parameter to 'high' if requested
• Adjust prompts only if user explicitly requests changes
• Use XML tags to integrate prompt snippets thoughtfully
• Fix tool overtriggering by softening aggressive language
• Prevent over-engineering with specific prompt snippets
• Improve code exploration and frontend design as needed
