The server dropped the ?token=<key> query-param WS auth in favor of a
first-message {"type":"auth","token":...} handshake that must complete
within 3 s, so the old query-param connection silently timed out on the
server side and we reconnected every ~8 s in a tight loop.
Send the handshake right after ws_connect, wait up to 5 s for auth_ok,
and treat auth rejection as a connection error so the reconnect backoff
kicks in instead of hot-looping. Bumps manifest to 0.2.1.
HACS-compatible custom component split out from the main LedGrab repo.
Creates light, switch, sensor, number, and select entities for each
configured LedGrab device.
