[Bug] /context command reports 200K max for Claude Opus 4.6 instead of 1M

## Description The `/context` slash command reports a max context window of **200K tokens** for `claude-opus-4-6`, but per the [Opus 4.6 announcement](https://www.anthropic.com/news/claude-opus-4-6), the model supports a **1M token context window** (in beta). ## Current behavior ``` claude-opus-4-6 · 28k/200k tokens (14%) ``` ## Expected behavior ``` claude-opus-4-6 · 28k/1000k tokens (2.8%) ``` (Or similar — reflecting the actual 1M context window) ## Additional context - The 200K figure appears to be the threshold where premium API pricing begins, not the actual context limit. - This also affects the percentage calculations and the autocompact buffer sizing, which are both derived from the reported max. - The announcement states: *"And, in a first for our Opus-class models, Opus 4.6 features a 1M token context window in beta."* ## Environment - Claude Code (latest as of 2025-02-05) - Model: `claude-opus-4-6` - Platform: macOS (Darwin 24.6.0)
