Try this:

\completecontent

P.S. This works using ConTeXt ver: 2024.12.30 16:14 but fails using ConTeXt ver: 2025.02.07 20:46 (for me at least).
You've just been lucky then

\def\doPageNumber#1%
   {%\the\numexpr #1 - 1\relax\ · #1}% #1 is not a number
    %\the\numexpr \structurelistrealpagenumber - 1\relax\ · #1}
    \tointeger{\structurelistrealpagenumber - 1} · #1}

\setupcombinedlist[content][list={chapter}]

\setuphead
   [chapter]
   [expansion=yes]

\setuplist
   [chapter]
   [pagecommand=\doPageNumber]

\starttext
     \completecontent
     \page
     \doloopoverlist
       {one,two,three,four,five}
       {
         \chapter{Title \recursestring}
         \samplefile{tufte}
         \page
       }
\stoptext

#1 is a 'typeset number' so even if it expands (not always btw) to soem 
digit you get something but then if also some relax creeps in the 
\numexpr scanning stops prematurely

you also (likely) want that one, two etc in the list
