HAL v3.4 extends the range notify from 8→12 bytes:
[0-3] int32 LE front_mm
[4-7] int32 LE back_mm
[8-11] float32 LE best_rssi dBm (NEW)
Parser now handles both lengths (8=v3.3, 12=v3.4) by detecting
packet size. RSSI is extracted as Double and assigned to both
Front and Back anchors (shared signal quality); nil for v3.3.
UI already conditionally renders rssiString (guard on Optional).
Added Data.readFloat32LE(at:) helper using IEEE 754 bit-pattern
reinterpretation (little-endian UInt32 → Float(bitPattern:)).
