refactor(cli): address code review feedback

- Abstracted hardcoded padding, margin, and width calculations in `DenseToolMessage` into explicit constants to improve readability.
- Made `terminalWidth` a required property on `DenseToolMessageProps` to ensure consistent layout calculations, simplifying internal ternary checks.
- Updated `DenseToolMessage` tests to provide the now-required `terminalWidth` prop.
- Removed expensive `node:crypto` usage in `DiffRenderer` key generation, opting for a simpler optional key.
- Simplified terminal refresh logic in `AppContainer` by removing `setTimeout` from the "show more lines" handler, as it was redundant.
- Streamlined `staticHeight` calculation loop in `ToolGroupMessage` to use layout constants.
- Removed redundant `height={0}` properties on Box borders in `ToolGroupMessage`.
- Simplified `effectiveMaxHeight` assignment in `ToolResultDisplay` by using the pre-calculated `availableHeight` directly.
- Restore tool message padding by moving `paddingTop={1}` from `ToolMessage` and `ShellToolMessage` content boxes back to `paddingBottom={1}` in `StickyHeader`.
- Restore `ToolConfirmationQueue` layout.
- Removed excluded file information from ReadManyFiles tool's compact output
