React & Ink (CLI UI)

• Side Effects: Use reducers for complex state transitions; avoid setState triggers in callbacks.
• Always fix react-hooks/exhaustive-deps lint errors by adding the missing dependencies.
• Shortcuts: only define keyboard shortcuts in packages/cli/src/config/keyBindings.ts
• Do not implement any logic performing custom string measurement or string truncation. Use Ink layout instead leveraging ResizeObserver as needed.
• Avoid prop drilling when at all possible.

Testing

• Utilities: Use renderWithProviders and waitFor from packages/cli/src/test-utils/.
• Snapshots: Use toMatchSnapshot() to verify Ink output.
• Mocks: Use mocks as sparingly as possible.
