The following is pure guess, as I've never used ConTeXt myself: if you  
look at the ConTeXt ReadMe file

/usr/local/texlive/2008/texmf-dist/doc/context/document/general/ 
manuals/mreadme.pdf

it's in Lucida, and its sources seem to be

/usr/local/texlive/2008/texmf-dist/doc/context/manuals/allkind/ 
mcommon.tex
/usr/local/texlive/2008/texmf-dist/doc/context/manuals/allkind/ 
mreadme.tex

the first containing macros and the second the actual readme.

The calls to the Lucida fonts seem to reside in mcommon.tex. Based on  
them, I would correct your file to

\usetypescriptfile[type-buy]
\usetypescript[lucida][texnansi]
\setupbodyfont[lucida,10pt]
\setupheadertexts[]
\starttext
Hello world.
\showbodyfont[lbr]
\stoptext

That works apparently better, in that there are calls to specific  
metrics such as texnansi-lbr, but that still doesn't work completely,  
as this metrics isn't defined and ConTeXt looks for MetaFont sources  
which it doesn't find. For Lucida Bright Regular in TeXnANSI encoding  
(aka LY1) I've the metrics lbr and hlhr8y defined in my Lucida map  
files lucida.map and lucidabr-o.map, while ConTeXt is looking for  
texnansi-lbr.

This is confirmed by

/usr/local/texlive/2008/texmf-dist/tex/context/base/type-buy.tex

containing apparently support for commercial fonts and in particular

% Lucida Bright : Biggelow and Holmes

\starttypescript [serif] [lucida] [name]
     \definefontsynonym [Serif]            [LucidaBright]
     \definefontsynonym [SerifBold]        [LucidaBright-Demi]
     \definefontsynonym [SerifItalic]      [LucidaBright-Italic]
     \definefontsynonym [SerifSlanted]     [LucidaBright-Oblique]
     \definefontsynonym [SerifBoldItalic]  [LucidaBright-DemiItalic]
     \definefontsynonym [SerifBoldSlanted] [LucidaBright-DemiItalic]
     \definefontsynonym [SerifCaps]        [LucidaBrightSmallcaps]
     \definefontsynonym [SerifBoldCaps]    [LucidaBrightSmallcaps-Demi]
\stoptypescript

[...]

\starttypescript [serif] [lucida] [texnansi,ec,8r]
     \definefontsynonym [LucidaBright]               [\typescriptthree- 
lbr]   [encoding=\typescriptthree]
     \definefontsynonym [LucidaBright-Demi]          [\typescriptthree- 
lbd]   [encoding=\typescriptthree]
     \definefontsynonym [LucidaBright-DemiItalic]    [\typescriptthree- 
lbdi]  [encoding=\typescriptthree]
     \definefontsynonym [LucidaBright-Italic]        [\typescriptthree- 
lbi]   [encoding=\typescriptthree]
     \definefontsynonym [LucidaBrightSmallcaps]      [\typescriptthree- 
lbrsc] [encoding=\typescriptthree]
     \definefontsynonym [LucidaBrightSmallcaps-Demi] [\typescriptthree- 
lbdsc] [encoding=\typescriptthree]
     \definefontsynonym [LucidaBright-Oblique]       [\typescriptthree- 
lbsl]  [encoding=\typescriptthree]
\stoptypescript

So it seems the syntax is pretty much fixed and requires metrics in  
the form texnansi-lbr, ec-lbr or 8r-lbr, none of which is defined in  
the Lucida map files that I have (and I can see no such file in  
MacTeX-2008).

So I would say the ConTeXt support files for the Lucida fonts are  
missing. You can double check, in case you have gwTeX, by looking in  
texmf.gwtex at the ConTeXt support files for the gtamacfonts: there  
are many of them, and they seem to follow the above pattern.

Going further might be a question for a ConTeXt user mailing list if  
any.

Hope this helps (a bit),
