Package layout note: the repo is a flat monorepo -- every package lives directly under packages/<name> (there is no packages/v1/ or packages/v2/ directory). v2 ships from the /v2 subpath of the same packages: v2 React is @copilotkit/react-core/v2 (source: packages/react-core/src/v2/) and v2 runtime is @copilotkit/runtime/v2 (source: packages/runtime/src/v2/). There is no @copilotkit/react or @copilotkit/agent package -- BuiltInAgent and the v2 agent definitions are re-exported from @copilotkit/runtime/v2 (source: packages/runtime/src/agent/).
