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 introduces several changes to better manage terminal height and prevent UI tearing, especially when displaying long tool outputs or when the pending history item exceeds the available terminal height.
- Calculate and utilize available terminal height in `App.tsx`, `HistoryItemDisplay.tsx`, `ToolGroupMessage.tsx`, and `ToolMessage.tsx`.
- Refresh the static display area in `App.tsx` when a pending history item is too large, working around an Ink bug (see https://github.com/vadimdemedes/ink/pull/717).
- Truncate long tool output in `ToolMessage.tsx` and indicate the number of hidden lines.
- Refactor `App.tsx` to correctly measure and account for footer height.

- Refactors history display using Ink's <Static> component to prevent flickering and improve performance by rendering completed items statically.
- Introduces ConsolePatcher component to capture and display console.log, console.warn, and console.error output within the Ink UI, addressing native handling issues.
- Introduce a new content splitting mechanism to work better for static items. Basically when content gets too long we will now split content into multiple blocks for Gemini messages to ensure that we can statically cache larger pieces of history.
