[Feature Request] Increase Claude Code context window to 500k+ tokens on higher-tier plans

Bug Description
Right now, on the Max x20 plan, Claude Code supports a context window of about 200k tokens. At the same time, Gemini 3 already offers a 1M token context window. For tasks like working with large codebases, long debugging sessions, and refactoring across many files, 200k tokens is often not enough. I frequently have to manually trim context or split work into smaller chunks, which breaks the flow and reduces productivity.

It would be amazing if you could increase the Claude Code context window to at least around 500k tokens on higher-tier plans. This would:

• Make it much easier to work with real-world repositories without manual context management
• Reduce the need to constantly re-upload or re-explain parts of the project
• Help Claude stay competitive with other models that already provide much larger context windows
