`gofmt -w cli/` — trailing newlines, minor whitespace alignment. Caught during PR-readiness review (`gofmt -l .` had been non-clean since the em-dash → ASCII bulk replace earlier in the v0.4 series).

//
|
|
// yes=true → proceed (explicit user opt-in via -y/--yes)
|
|
// non-TTY OR jsonOut → return CodeInputConfirmationRequired (exit 10);

// always require explicit confirmation in scripted contexts, never silent
|

// proceed. See cli/README.md "Exit codes".
|
|
//
|
|
// `yes` should be sourced from the persistent global -y/--yes flag.
