Hand-encoded byte sequences for RadioConfig, every Command tag, and
every Response tag, taken directly from the spec. Fields use hex-clean
values (freq_hz = 0x12345678, sync_word = 0xABCD, etc.) so each
little-endian byte is visually verifiable.
Locks firmware and host to the written spec — a refactor that quietly
changes a field layout fails here, not in the field.
Ten properties covering: RadioConfig roundtrip and validate/resolve
determinism; no-panic on arbitrary bytes for both Command::from_bytes
and RadioConfig::from_bytes; bounded-capacity for Transmit payloads
(guards the heapless::Vec size); Command roundtrip via a test-only
encoder (the library only decodes commands); COBS reversibility; and
two streaming CobsDecoder properties (no-panic on random byte streams
with random chunk boundaries, and a full encode→feed→decode roundtrip).
Adds Clone to Command and Response — benign public-API expansion that
unblocks proptest's Just strategy.
