[Bug] /model /sessions command TUI selector has extremely low text contrast on macOS terminal (v0.8.64)

[Yanzk]

Description

When using either the /model or /session commands to open the selection popup, the contrast between the text and the background is extremely low, making the options very hard to read. However, the /config command window displays text correctly. I suspect the underlying UI library used for rendering these list selectors is failing to correctly adapt to the system terminal theme colors, leading to a conflict between foreground and background colors.

Chinese:
使用 /model 和 /session 命令弹出选择窗口时，文字和背景的对比度极低，导致文字难以看清。但使用 /config 命令弹出的配置窗口显示正常。我推测用于渲染列表选择的底层 UI 库未能正确适配系统终端主题颜色，导致出现前景色/背景色混淆的问题。

Steps to reproduce

1. Launch codewhale in the terminal.
2. Type the command /model and press Enter, observe the popup (text is blurred).
3. Type the command /sessions and press Enter, observe the popup (text is blurred as well).

Chinese:

1. 在终端中启动 codewhale。
2. 输入命令 /model 并回车，观察弹窗（文字模糊）。
3. 输入命令 /sessions 并回车，观察弹窗（文字同样模糊）。

Expected behavior

I expect the color scheme of the /model window to be consistent with the /config window, ensuring sufficient high contrast between the foreground text and background for easy readability.

期望 /model 窗口的配色能与 /config 窗口保持一致，确保前景色和背景色有足够的高对比度，方便阅读。

Actual behavior

Impact

Environment

• codewhale version: v0.8.64
• OS: macOS (Tested with the Pro1 theme. Also switched to Pro, ClearDark, and Homebrew themes, but the issue persists.)
• Shell: zsh (macOS default)
• Terminal app: macOS native Terminal.app
  Chinese:
• codewhale version: v0.8.64
• OS: macOS (Pro1主题下测试，也切换过 Pro, ClearDark, Homebrew 主题测试，问题依旧)
• Shell: zsh (macOS 自带)
• Terminal app: 原生 macOS 终端 (Terminal.app)

Thanks @Yanzk for the report.

This issue is staying open for maintainer triage. CodeWhale gets better because people bring us real edge cases from real machines, providers, regions, and workflows.

If you can add a reproduction, logs, version output, screenshots, or the provider/model involved, that makes it much easier for us to verify and harvest the fix. Maintainers may comment /lgtmi to mark recurring issue reporters as approved so this intake note is skipped next time.

Triage note: moving this into v0.8.66 and linking it to the broader visual QA work in #3487 / #3480. This should become a fixture in the terminal visual regression matrix rather than a one-off contrast tweak.
