dailz 92760dd8ee fix(state_portal): make shutdown() idempotent to prevent duplicate log lines (#22) ...

shutdown() fired twice on exit (explicit call in main.rs + Drop impl), causing "Total: N frames" and "StatePortal shutdown complete" to log twice 23us apart. Add `shutdown_started: bool` guard at function entry.

Plain bool (not AtomicBool) because &mut self already grants exclusive access. Guard is set BEFORE cleanup so Drop re-entry during panic unwinding is suppressed.

Includes scripts/test_shutdown_idempotency.sh as a live regression test (requires Wayland session). Verified PASS on KWin: both lines print exactly once.
