Closes #29390
Type of change
What does this PR do?
The CLI .fail() handler receives the error message in
msgbut never writes it to stderr before showing help. AddedUI.error(msg)beforecli.showHelp(show)so users see what argument was wrong.How did you verify your code works?
Ran
bun run ./src/index.ts --unknown-flagand confirmed the output now showsError: Unknown arguments: unknown-flagbefore the help text.Screenshots / recordings
