Against real-world OTP 26 peers the v6 handshake "succeeded" but the first REG_SEND silently dropped on the peer side — peer accepted the connection then closed the link with no bytes when we tried to call a registered process. Hit during MPS↔portal wallet RPC smoke test. Root cause: OTP 25+ requires DFLAG_MANDATORY_25_DIGEST to be present in our advertised flag set. The digest is the hash of the OTP-25 mandatory flag set; without it the peer's dist driver loses confidence in the negotiation and drops messages from us without surfacing an error. Adds DFLAG_MANDATORY_25_DIGEST to DEFAULT_FLAGS. Also extends _decode_message to accept both legacy pass-through (0x70 ...) and dist-header framing (0x83 0x44 0x00 ...) on receive — modern OTP may send dist-headed messages even when we didn't negotiate DFLAG_DIST_HDR_ATOM_CACHE. Fragments (0x83 0x45 / 0x83 0x46) still TODO; we surface a clear ChannelError instead of silent corruption. Send side still uses pass-through framing — we don't yet implement the atom-cache encode/decode that DFLAG_DIST_HDR_ATOM_CACHE would require. Peer routes our pass-through sends without issue. 122/122 tests pass including live integration against a local Erlang node and the TLS dist suite.
