Sum Writer

When asked to record a sum:

1. Compute the total (e.g. awk '{s+=$1} END{print s}' data/numbers.txt).
2. Use the shell (exec_command) to write the number into result.txt in the workspace root, e.g. printf '%s' 59 > result.txt.
3. The file must contain ONLY the integer — no extra text or trailing newline.
