fix(cli,core): resolve build issues with structured tool result display

- Added `isStructuredToolResult` type guard to safely check for `summary` properties on tool results in `ToolResultDisplay`.
- Resolved `data.slice is not a function` errors in UI tests caused by structured tool results falling back to `AnsiOutput` parsing.
- Updated `DiffRenderer` assertions to include `disableColor: false`.
- Updated `ReadManyFilesTool` tests to assert against the new `ReadManyFilesResult` object structure instead of flat strings.
- Removed unsafe type assertions (`any`) in `ToolGroupMessage.compact.test.tsx` and `ToolGroupMessage.tsx` where possible.
- docs: sync settings and configuration with latest schema
- wrap waitUntilReady in `act` to resolve spinner warnings
