Release v2.0.0

What's Changed

🔌 Persistent TCP Connection

This release upgrades to the latest version of pyasyncialarm, which introduces a persistent TCP connection to the alarm panel. The connection is now kept open across requests and automatically re-established if it drops, with one transparent retry before surfacing an error.

In practice this means:

• Fewer TCP handshakes per poll cycle
• No more unavailable state caused by OSError during socket receive
• More resilient behaviour when the panel is slow or temporarily unreachable

🐛 Bug Fixes

• Zone sensor false positives — _has_alarm and _has_anomaly flags are now reset at the start of every coordinator update cycle. Previously, once a zone triggered an alarm or anomaly, the sensor would remain in that state even after the zone returned to normal.
• CANCEL state now mapped correctly — when the panel returns DevStatus=3 (cancel/clear), the alarm control panel entity now shows disarmed instead of an unknown/unavailable state.
• async_shutdown closes the socket — the coordinator now calls ialarm_device.shutdown() when Home Assistant stops, ensuring the TCP connection is cleanly closed instead of being left open.

✨ Improvements

• Smarter disarm sequence — async_alarm_disarm now uses disarm_and_cancel() from the library, which reads the DevStatus from the panel response and only retries cancel_alarm if the panel is still in a triggered state. The previous fixed asyncio.sleep(2) has been removed.
• Device trigger cancel — a new device trigger is available for automations: fires when the alarm alerts are canceled via the dedicated button.
• DOMAIN no longer hardcoded in device_trigger.py — imported from const.py to avoid silent drift if the domain name changes.
• Redundant async_set_updated_data call removed from _async_update_data in the coordinator.
• Residual hass.data.setdefault removed from __init__.py — leftover from an older integration pattern, superseded by config_entry.runtime_data.

📦 Dependencies

• Requires the new version of pyasyncialarm with persistent TCP connection support.
