Covers the "Connecting to server" / xhr-poll-error hang (stale server URL,
fixed via Clear data + re-provision), and adb-over-Wi-Fi setup including the
gotchas: must be on the same subnet, and never `adb root` over a wireless
connection (it wedges adbd until reboot). Linked from the README Device Setup
section.
