This commit addresses several code review comments primarily focused on improving the rendering and stability of the CLI UI.
Key changes include:
- Passing `isPending` and `availableTerminalHeight` props to `MarkdownDisplay` to enable more intelligent rendering of content, especially for pending messages and code blocks.
- Adjusting height calculations in `ToolGroupMessage` and `ToolMessage` to more accurately reflect available space.
- Refining the logic in `App.tsx` for measuring and utilizing terminal height, including renaming `footerRef` to `mainControlsRef` for clarity.
- Ensuring consistent prop drilling for `isPending` and `availableTerminalHeight` through `HistoryItemDisplay`, `GeminiMessage`, and `GeminiMessageContent`.
- In `MarkdownDisplay`, when `isPending` is true and content exceeds `availableTerminalHeight`, the code block will now be truncated with a "... generating more ..." message. If there's insufficient space even for the
message, a simpler "... code is being written ..." will be shown.
- This commit refactors the Markdown rendering logic within the CLI UI.
The existing `MarkdownRenderer.tsx` class-based component has been
replaced with a new functional component `MarkdownDisplay.tsx`.
- The `MarkdownDisplay` component is a React.memoized component for
improved performance and maintains the same core Markdown parsing
and rendering capabilities.
