The winget jq build on Windows emits CRLF; a trailing \r silently corrupts
`for x in $(jq ...)` loops and read-from-@tsv fields (single-value $() hides it).
Fix: override `jq(){ command jq "$@" | tr -d '\r'; }`. Windows-build-specific,
so it passes review on Mac/Linux. First hit + fix: the self-check skill engine.
