/**
 * Tests for WorkspaceKeyInput.tsx
 *
 * Covers (per plan):
 * - Input echo mask: raw key chars never appear in output
 * - Wrong prefix shows inline error
 * - Key too short disables Enter (validateKey returns error)
 * - Esc cancel hint present in rendered output
 * - Shows "Saving..." when saving prop is true
 * - Shows saveError when provided
 *
 * Note on renderToString: WorkspaceKeyInput calls useInput which registers a stdin
 * listener that prevents Ink from exiting. We therefore skip Ink rendering tests
 * and instead verify the component's behaviour through pure validation logic tests
 * plus a direct JSX snapshot check against a minimal stub render.
