v0.2.1

Fix: bundled card resource not registered on HA 2026.7+

HA 2026.7 renamed LovelaceData.mode to resource_mode, which broke v0.2.0's storage-mode check — the card resource was never auto-registered, causing a "Custom element doesn't exist: parcelapp-card" dashboard error after removing the standalone card.

Registration now detects a writable resource collection directly (duck-typing on async_create_item) instead of reading a mode attribute, so it works on both pre- and post-2026.7 Home Assistant.

If you hit the error on v0.2.0: update to this release and restart Home Assistant — the resource registers automatically. A hard browser refresh may be needed afterwards.
