/**
 * Tests for `pieui card check-sync` — config handling and delegation.
 *
 * Critical invariants:
 *  - Non-interactive shell without backendProjectDir in config → descriptive
 *    error message, exits without spawning python.
 *  - Reads backendProjectDir from .pie/config.json.
 *  - Does NOT read the `python` envelope (TS side is just a proxy).
 *  - Returns exit code 0 on success, 1 on failure.
