The blocking WiFiClient.connect() ran on the main loop and stalled it for the lwIP default (~18.5s) when the host was unreachable -- including the DNS lookup -- freezing the UI, so the screen took ~10s to wake. The 2-arg connect() also ignored CONNECT_TIMEOUT_MS (that only bounds reads). Move only the blocking connect() to a dedicated FreeRTOS task. read/write/frame stay on the main loop exactly as before (unchanged low-latency data path -- the link/Resource timing is untouched). An atomic _conn_state hands _client ownership between the task (while CONNECTING) and the main loop (while CONNECTED) so they never touch the socket concurrently. Bound the connect via the 3-arg connect() and back off retries to 15s. tests/hardware: wait_for_tcp_link() matched "started", keying on interface startup rather than the actual connect. With the async connect that let the harness drive the announce before the link was up, so the device's announce was lost and the first direct message (bz2-probe) failed. Match "connected to". Verified on a T-Deck: screen wake instant (connect off the main loop); e2e smoke 5/5 including bz2-on-receive.
