docs(skill): say where opencode was measured, and the rc 3 leftover

The opencode readiness and marker measurements were made on Linux, not
on a Mac, and the docs now say so. A worker whose pane ends after it
wrote its answer file but before the marker matched answers 3 with no
answer: the rc 3 row now says the file may still be in its folder. The
example's input folder is named input, so the prompt reads cleanly.
