Brand consistency: the device now advertises as "Clawdmeter". Updated the
three functional spots that must agree for discovery-by-name to work —
ble.cpp DEVICE_NAME (advertised) and both daemons' DEVICE_NAME (scan match) —
plus the README/CLAUDE.md/install-script references (and fixed the stray
"Claudemeter" typo in the README).
Note: hosts cache the GATT name, so an already-paired device keeps showing the
old name until removed/re-paired (bluetoothctl remove <mac>).
