Opportunistic (non-link) delivery must strip dest_hash from the LXMF
payload — it's carried by the RNS packet header. Python prepends it
back on receive; we now do the same. Previously ratdeck always included
dest_hash when sending and never prepended it when receiving, breaking
interop in both directions.
- packFull: return [src:16][sig:64][msgpack] instead of [dest:16][src:16][sig:64][msgpack]
- onPacketReceived: prepend dest_hash from packet header before unpacking
- sendDirect: use messageId computed by packFull instead of re-hashing wire payload
- Add docs/WIRE-FORMAT.md documenting the exact format for all delivery methods
