mecatui: incorrect context-window sizes in /models and the info bar

Version

v0.0.23-23-ga4c2d008

Description

Model context-window sizes are displayed incorrectly in both the /models list and the info bar after selecting a model.

For example, Astra is shown with a 128K-token context window, whereas its context window is 1.05M tokens.

Steps to reproduce

1. Open mecatui.
2. Run /models.
3. Inspect the context-window size displayed for Astra.
4. Select Astra and inspect the context-window size in the info bar.

Actual behavior

Both the /models list and the info bar display Astra’s context window as 128K tokens.

Expected behavior

Both surfaces should display Astra’s context window as 1.05M tokens. Other models should likewise show accurate context-window sizes.

Impact

Incorrect context limits make it difficult to compare models, select one with sufficient capacity, and understand the available context for the active model.
