 * Vitest reporter for `@arizeai/phoenix-client/vitest`.
 *
 * The reporter does not replace Vitest's default test output. Instead it
 * appends a Phoenix-flavored summary at the end of the run that lists
 * outputs, annotations, and dataset/experiment links for each suite.
 *
 * The class implements the Vitest `Reporter` interface structurally rather
 * than nominally so we don't have to import a CJS type from `vitest/reporters`.
