Decode a broadcast trace message back into a Message object (DX-1125). The wire payload
drops both ref meta fields (see encodeMetaForWire), so tags — the broadcast envelope's
tag list — is required to restore them: trigger addresses work for cancellation, and
conversation is what matchesFilter compares, so a subscription filtered by it matches
nothing without this. Restored refs are address-only (.uri); they are never resolved.
