TOON encodes `{}` as the empty string, so shortest-wins picked it over `{}` and
the tool result went out with content[{type:'text',text:''}]. Clients reject that
outright — the beta MCP endpoint answers such a call with
Anthropic Proxy: Invalid content from server
which reads as a transport fault rather than "this endpoint returned no data",
and there is nothing in the error naming the tool or the payload.
chooseToolText now only takes the shorter encoding while something is left to
read, and successResult renders a bodyless success (204, empty handler return)
as "(no content)" instead of an empty block. structuredContent is untouched: it
is still derived from the original JSON.
Found while reading beta through the MCP to confirm the dicom-viewer client's
webOrigins. Any admin GET that legitimately returns {} hits this.
