/**
 * Shared module mock for @clack/prompts.
 *
 * Same singleton pattern as auth-flow-mock.ts so that any test file
 * importing this helper installs the mock exactly once for the whole
 * `bun test` process. The interactive `text()` / `select()` are steerable
 * via clackMockState; `note()` messages are captured for assertions.
 *
 * The mock is harmless for tests that don't reach the interactive path —
 * it only replaces the module, and every call site is covered below.
